Alignment and fill options only apply to numbers.
Rework the implementation to mainly branch on the format string rather
than the type information. This is more straightforward to maintain and
more straightforward for comptime evaluation.
Enums support being printed as decimal, hexadecimal, octal, and binary.
`formatInteger` is another possible format method that is
unconditionally called when the value type is struct and one of the
integer-printing format specifiers are used.

added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly
- no fmt string

These conversion routines accept a `round` argument to control how the
result is rounded and return whether the result is exact. Most callers
wanted this functionality and had hacks around it being missing.
Also delete `std.math.big.rational` because it was only being used for
float conversion, and using rationals for that is a lot more complex
than necessary. It also required an allocator, whereas the new integer
routines only need to be passed enough memory to store the result.

Update the estimated total items for the codegen and link progress nodes
earlier. Rather than waiting for the main thread to dispatch the tasks,
we can add the item to the estimated total as soon as we queue the main
task. The only difference is we need to complete it even in error cases.

When the name strategy is `.parent`, the DWARF info really wants to know
what `Nav` we were named after to emit a more optimal hierarchy.

* The `codegen_nav`, `codegen_func`, `codegen_type` tasks are renamed to
`link_nav`, `link_func`, and `link_type`, to more accurately reflect
their purpose of sending data to the *linker*. Currently, `link_func`
remains responsible for codegen; this will change in an upcoming
commit.
* Don't go on a pointless detour through `PerThread` when linking ZCU
functions/`Nav`s; so, the `linkerUpdateNav` etc logic now lives in
`link.zig`. Currently, `linkerUpdateFunc` is an exception, because it
has broader responsibilities including codegen, but this will be
solved in an upcoming commit.

In particular, this allows importing `build.zig.zon` at comptime.

This came with a big cleanup to `Zcu.PerThread.updateFile` (formerly
`astGenFile`).
Also, change how the cache manifest works for files in the import table.
Instead of being added to the manifest when we call `semaFile` on them,
we iterate the import table after running the AstGen workers and add all
the files to the cache manifest then.
The downside is that this is a bit more eager to include files in the
manifest; in particular, files which are imported but not actually
referenced are now included in analysis. So, for instance, modifying any
standard library file will invalidate all Zig compilations using that
standard library, even if they don't use that file.
The original motivation here was simply that the old logic in `semaFile`
didn't translate nicely to ZON. However, it turns out to actually be
necessary for correctness. Because `@import("foo.zig")` is an
AstGen-level error if `foo.zig` does not exist, we need to invalidate
the cache when an imported but unreferenced file is removed to make sure
this error is triggered when it needs to be.
Resolves: #22746

This commit allows using ZON (Zig Object Notation) in a few ways.
* `@import` can be used to load ZON at comptime and convert it to a
normal Zig value. In this case, `@import` must have a result type.
* `std.zon.parse` can be used to parse ZON at runtime, akin to the
parsing logic in `std.json`.
* `std.zon.stringify` can be used to convert arbitrary data structures
to ZON at runtime, again akin to `std.json`.
