This is fairly straightforward; the actual compiler changes are limited
to the CLI, since `Compilation` already supports this combination.
A new `std.Build` API is introduced to allow representing this. By
passing the `emit_object` option to `std.Build.addTest`, you get a
`Step.Compile` which emits an object file; you can then use that as you
would any other object, such as either installing it for external use,
or linking it into another step.
A standalone test is added to cover the build system API. It builds a
test into an object, and links it into a final executable, which it then
runs.
Using this build system mechanism prevents the build system from
noticing that you're running a `zig test`, so the build runner and test
runner do not communicate over stdio. However, that's okay, because the
real-world use cases for this feature don't want to do that anyway!
Resolves: #23374
Compile log output is now separated based on the `AnalUnit` which
perfomred the `@compileLog` call, so that we can omit the output for
unreferenced ("dead") units. The units are also sorted when collecting
the `ErrorBundle`, so that compile logs are always printed in a
consistent order, like compile errors are. This is important not only
for incremental compilation, but also for parallel analysis.

* Fix compile error in Fuzzer web-ui
The error was:
```
error: expected type '?mem.Alignment', found 'comptime_int'
```
* Apply suggestions from code review
`.of` call is shorter and clearer

std.crypto: add constant-time codecs
Add constant-time hex/base64 codecs designed to process cryptographic
secrets, adapted from libsodium's implementations.
Introduce a `crypto.codecs` namespace for crypto-related encoders and
decoders. Move ASN.1 codecs to this namespace.
This will also naturally accommodate the proposed PEM codecs.
This lays the groundwork for #2879. This library will be built and linked when a
static libc is going to be linked into the compilation. Currently, that means
musl, wasi-libc, and MinGW-w64. As a demonstration, this commit removes the musl
C code for a few string functions and implements them in libzigc. This means
that those libzigc functions are now load-bearing for musl and wasi-libc.
Note that if a function has an implementation in compiler-rt already, libzigc
should not implement it. Instead, as we recently did for memcpy/memmove, we
should delete the libc copy and rely on the compiler-rt implementation.
I repurposed the existing "universal libc" code to do this. That code hadn't
seen development beyond basic string functions in years, and was only usable-ish
on freestanding. I think that if we want to seriously pursue the idea of Zig
providing a freestanding libc, we should do so only after defining clear goals
(and non-goals) for it. See also #22240 for a similar case.
