+ clean some @as()

Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change

"SHT_NOBITS" sections can be easily moved around in the file, they can be anywhere since there is no data...
and remove logic about the categorization of symbol tables:
I don't understand or remember why it was needed,
and, in my tests, it works fine without...
It previouly failed to strip an exe linked with `mold`

Anecdote 1: The generic version is way more popular than the non-generic
one in Zig codebase:
git grep -w alignForward | wc -l
56
git grep -w alignForwardGeneric | wc -l
149
git grep -w alignBackward | wc -l
6
git grep -w alignBackwardGeneric | wc -l
15
Anecdote 2: In my project (turbonss) that does much arithmetic and
alignment I exclusively use the Generic functions.
Anecdote 3: we used only the Generic versions in the Macho Man's linker
workshop.

parts of the code are independant of Elf32/Elf64 variant, so avoid
generating the code twice by putting them outside of the generic struct.

Seems the right thing to do, but not strictly necessary.

as documented at
https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html
It is now equivalent to do
```
zig objcopy --only-keep-debug bar foo.debug
zig objcopy -g bar foo.tmp
zig objcopy --add-gnu-debuglink=foo.debug foo.tmp foo
rm foo.tmp
```
or
```
zig objcopy --only-keep-debug bar foo foo.debug
zig objcopy -g --add-gnu-debuglink=foo.debug bar foo
```
or
```
zig objcopy -g --extract-to=foo.debug bar foo
```

Support for the use case:
`zig objcopy --strip-all program stripped --extract-to stripped.dbg`
to separate the debug & symbols sections out to a companion file, with a corresponding a .gnu_debuglink.
note: this is "a minimal effort implementation"
It doesn't support all possibile elf files: there may be some sections type that need fixups, the program header may need fix up, ...
It was written for a specific use case (strip debug info to a sperate file, for linux 64-bits executables built with `zig` or `zig c++` )
It doesn't support 32-bit files, or file with non-native endianess.

std.Build.addTest creates a CompileStep as before, however, this kind of
step no longer actually runs the unit tests. Instead it only compiles
it, and one must additionally create a RunStep from the CompileStep in
order to actually run the tests.
RunStep gains integration with the default test runner, which now
supports the standard --listen=- argument in order to communicate over
stdin and stdout. It also reports test statistics; how many passed,
failed, and leaked, as well as directly associating the relevant stderr
with the particular test name that failed.
This separation of CompileStep and RunStep means that
`CompileStep.Kind.test_exe` is no longer needed, and therefore has been
removed in this commit.
* build runner: show unit test statistics in build summary
* added Step.writeManifest since many steps want to treat it as a
warning and emit the same message if it fails.
* RunStep: fixed error message that prints the failed command printing
the original argv and not the adjusted argv in case an interpreter
was used.
* RunStep: fixed not passing the command line arguments to the
interpreter.
* move src/Server.zig to std.zig.Server so that the default test runner
can use it.
* the simpler test runner function which is used by work-in-progress
backends now no longer prints to stderr, which is necessary in order
for the build runner to not print the stderr as a warning message.

This commit extracts out server code into src/Server.zig and uses it
both in the main CLI as well as `zig objcopy`.
std.Build.ObjCopyStep now adds `--listen=-` to the CLI for `zig objcopy`
and observes the protocol for progress and other kinds of integrations.
This fixes the last two test failures of this branch when I run
`zig build test` locally.

Do not return stack local data for hex record payload data.

This commit moves the logic from `std.build.InstallRawStep` into `zig
objcopy`. The options here are limited, but we can add features as
needed.
closes #9261
New issues can be opened for specific objcopy flag support.
