wasi: fix wasm-wasi-musl constants
...
Zig's copy of the `SYMLINK_{NO,}FOLLOW` constants from wasi-musl was
wrong, as were the `IFIFO` and `IFSOCK` file type flags. Fix these up,
and add comments pointing to exactly where they come from (as the
wasi-musl source has lots of unused, different definitions of these
constants).
Add tests for the Zig convention that WASM preopen 3 is the current
working directory. This is true for WASM with or without libc.
Enable several fs and posix tests that are now passing (not necessarily
because of this change) on wasm targets.
Fixes #20890 .

The UEFI spec only does this because C doesn't have namespaces, we don't

std.heap.SmpAllocator: back to simple free

std.heap.SmpAllocator: alternate freelist accounting
...
Freelist length accounting in alloc had a negative impact, especially
with the integer type bumped up to u16, so I changed the system to be
based on counting slabs rather than total allocations.
