  [libc] Support configurable errno modes (#98287)

Rather than selecting the errno implementation based on the platform
which doesn't provide the necessary flexibility, make it configurable.

The errno value location is returned by `int *__llvm_libc_errno()` which
is a common design used by other C libraries.
