Yaxun (Sam) Liu 43d6e3874e [compiler-rt] Expose shared DSO helpers for compiler-rt runtimes (#191098) ...

The motivation of this PR is to refactor and expose DSO helper functions
so
they can be used by all compiler-rt libraries, including the profile
library,
without duplicating dlopen/dlsym (non-Windows) or
LoadLibrary/GetProcAddress
(Windows) logic in each runtime.

Implement the helpers in namespace __interception in
interception_linux.cpp for
non-Windows targets and interception_win.cpp for Windows, and use them
from the
existing Linux interception path for RTLD_NEXT/RTLD_DEFAULT/dlvsym
lookups.

This is NFC for existing libraries that already use interception's
public APIs;
sanitizer and interception lit behavior is unchanged.
