`std.Io.tty.Config.detect` may be an expensive check (e.g. involving
syscalls), and doing it every time we need to print isn't really
necessary; under normal usage, we can compute the value once and cache
it for the whole program's execution. Since anyone outputting to stderr
may reasonably want this information (in fact they are very likely to),
it makes sense to cache it and return it from `lockStderrWriter`. Call
sites who do not need it will experience no significant overhead, and
can just ignore the TTY config with a `const w, _` destructure.

std: Introduce `Io` Interface
|
|
As with Solaris (dba1bf935390ddb0184a4dc72245454de6c06fd2), we have no way to
actually audit contributions for these OSs. IBM also makes it even harder than
Oracle to actually obtain these OSs.

Let's keep passing this thing by pointer

this value should be calculated earlier and passed in

|
- ILSEQ -> error.BadPathName
- implement dirStatPath for WASI

|

only thing remaining is using libc dns resolution when linking libc
|

this feels better

There is no straightforward way for the Zig team to access the Solaris system
headers; to do this, one has to create an Oracle account, accept their EULA to
download the installer ISO, and finally install it on a machine or VM. We do not
have to jump through hoops like this for any other OS that we support, and no
one on the team has expressed willingness to do it.
As a result, we cannot audit any Solaris contributions to std.c or other
similarly sensitive parts of the standard library. The best we would be able to
do is assume that Solaris and illumos are 100% compatible with no way to verify
that assumption. But at that point, the solaris and illumos OS tags would be
functionally identical anyway.
For Solaris especially, any contributions that involve APIs introduced after the
OS was made closed-source would also be inherently more risky than equivalent
contributions for other proprietary OSs due to the case of Google LLC v. Oracle
America, Inc., wherein Oracle clearly demonstrated its willingness to pursue
legal action against entities that merely copy API declarations.
Finally, Oracle laid off most of the Solaris team in 2017; the OS has been in
maintenance mode since, presumably to be retired completely sometime in the 2030s.
For these reasons, this commit removes all Oracle Solaris support.
Anyone who still wishes to use Zig on Solaris can try their luck by simply using
illumos instead of solaris in target triples - chances are it'll work. But there
will be no effort from the Zig team to support this use case; we recommend that
people move to illumos instead.

The unit can now be specified in the argument.

For instance, when running a Zig test using the self-hosted aarch64
backend, this logic was previously expecting `std.zig.Server` to be
used, but the default test runner intentionally does not do this because
the backend is too immature to handle it. On 'master', this is causing
sporadic failures; on this branch, they became consistent failures.

The new `--error-style` option decides how build failures are printed.
The default mode "verbose" prints all context including the step graph
fragment and the failed command (if any). The alternative mode "minimal"
prints only the failed step itself, and does not print the failed
command. There are also "verbose_clear" and "minimal_clear" modes, which
have the distinction that the output is cleared (through ANSI escape
codes) between updates, preventing different updates from being confused
in the output. If `--error-style` is not specified, the environment
variable `ZIG_BUILD_ERROR_STYLE` is checked before falling back to the
default of "verbose"; this means the value can effectively be chosen
system-wide since it is generally a personal preference.
Also introduced is a `--multiline-errors` option which decides how to
print errors which span multiple lines. By default, non-initial lines
are indented to align with the first. Alternatively, a leading newline
can be printed to align everyting on the first column, or no special
treatment can be applied, resulting in misaligned output. Again, there
is an environment variable (`ZIG_BUILD_MULTILINE_ERRORS`) to specify a
preferred default if the option is not explicitly provided.
Resolves: #23472

Recording the command in a separate field will give the build runner
more freedom to choose how and when the command should be printed.

This is a major refactor to `Step.Run` which adds new functionality,
primarily to the execution of Zig tests.
* All tests are run, even if a test crashes. This happens through the
same mechanism as timeouts where the test processes is repeatedly
respawned as needed.
* The build status output is more precise. For each unit test, it
differentiates pass, skip, fail, crash, and timeout. Memory leaks are
reported separately, as they do not indicate a test's "status", but
are rather an additional property (a test with leaks may still pass!).
* The number of memory leaks is tracked and reported, both per-test and
for a whole `Run` step.
* Reporting is made clearer when a step is failed solely due to error
logs (`std.log.err`) where every unit test passed.

For now, there is a flag to `zig build` called `--test-timeout-ms` which
accepts a value in milliseconds. If the execution time of any individual
unit test exceeds that number of milliseconds, the test is terminated
and marked as timed out.
In the future, we may want to increase the granularity of this feature
by allowing timeouts to be specified per-step or even per-test. However,
a global option is actually very useful. In particular, it can be used
in CI scripts to ensure that no individual unit test exceeds some
reasonable limit (e.g. 60 seconds) without having to assign limits to
every individual test step in the build script.
Also, individual unit test durations are now shown in the time report
web interface -- this was fairly trivial to add since we're timing tests
(to check for timeouts) anyway.
This commit makes progress on #19821, but does not close it, because
that proposal includes a more sophisticated mechanism for setting
timeouts.
