On Windows, support Bun.stdin, Bun.stdout, Bun.stderr in Bun.write when the other argument is a file

[Jarred-Sumner]

What does this PR do?

The following now work as expected on Windows:

await Bun.write(Bun.stdout, Bun.file(path.join(import.meta.dir, "hello-world.txt")));
await Bun.write(Bun.stderr, Bun.file(path.join(import.meta.dir, "hello-world.txt")));

This also addresses a bug where we would have an assertion failure when passing a NUL file path on Windows. In most cases, we will now use the Windows GetFinalPathByHandleW function instead of Zig's implementation (ziglang/zig#18756).

Fixes #12404
Fixes #12134
Fixes #11352 (most likely)
Fixes #10914 (most likely)

How did you verify your code works?

The BUN_FEATURE_FLAG_DISABLE_UV_FS_COPYFILE environment variable forces the code path which does a read-write loop in Bun.write. We re-run the tests for Bun.write with this environment variable set on Windows. Also, added a couple more tests.
