platform specific error numbers, but these are platforms we do

[libc][errno] Use macro instead of system header (#91150)
## Why
Currently, the system header `errno.h` is included in `libc_errno.h`,
which is supposed to be consumed by internal implementations
[libc][errno] Use macro instead of system header (#91150)
## Why
Currently, the system header `errno.h` is included in `libc_errno.h`,
which is supposed to be consumed by internal implementations only. As
unit and hermetic tests should never use `#include <errno.h>` but
instead use `#include "src/errno/libc_errno.h"`, we do not want to
implicitly include `errno.h`. In order to have a clear seperation
between those two, we want to pull out the definitions of errno numbers
from `errno.h`.
## What
* Extract the definitions of errno numbers from
[include/errno.h.def](https://github.com/llvm/llvm-project/pull/91150/files#diff-ed38ed463ed50571b498a5b69039cab58dc9d145da7f751a24da9d77f07781cd)
and place it under
[include/llvm-libc-macros/linux/error-number-macros.h](https://github.com/llvm/llvm-project/pull/91150/files#diff-d6192866629690ebb7cefa1f0a90b6675073e9642f3279df08a04dcdb05fd892)
* Provide mips-specific errno numbers in
[include/llvm-libc-macros/linux/mips/error-number-macros.h](https://github.com/llvm/llvm-project/pull/91150/files#diff-3fd35a4c94e0cc359933e497b10311d857857b2e173e8afebc421b04b7527743)
* Find definition of mips errno numbers in glibc
[here](https://github.com/bminor/glibc/blob/ea73eb5f581ef5931fd67005aa0c526ba43366c9/sysdeps/unix/sysv/linux/mips/bits/errno.h#L32-L50)
(equally defined in the Linux kernel)
* Provide sparc-specific errno numbers in
[include/llvm-libc-macros/linux/sparc/error-number-macros.h](https://github.com/llvm/llvm-project/pull/91150/files#diff-5f16ffb2a51a6f72ebd4403aca7e1edea48289c99dd5978a1c84385bec4f226b)
* Find definition of sparc errno numbers in glibc
[here](https://github.com/bminor/glibc/blob/ea73eb5f581ef5931fd67005aa0c526ba43366c9/sysdeps/unix/sysv/linux/sparc/bits/errno.h#L33-L51)
(equally defined in the Linux kernel)
* Include proxy header `errno_macros.h` instead of the system header
`errno.h` in `libc_errno.h`/`libc_errno.cpp`
