Add a callback from interception to allow asan on Windows to produce
better error messages. If an unrecoverable error occured when
intercepting functions, print a message before terminating.
Additionally, when encountering unknown instructions, a more helpful
message containing the address and the bytes of the unknown instruction
is now printed to help identify the issue and make it easier to propose
a fix.
Depends on D149549

Do not treat unknown instructions as a fatal error. In most cases,
failure to intercept a function is reported by the caller, though
requires setting verbosity to 1 or higher to be visible.
Better error message reporting for asan will be added in a separate
patch.

These assembly patterns are needed to intercept some libc++ and
libunwind functions built by Clang for i686-w64-windows-gnu target.

To intercept the functions in Win11's ntdll.dll, we need to use the trampoline
technique because there are bytes other than 0x90 or 0xcc in the gaps between
exported functions. This patch adds more patterns that appear in ntdll's
functions.
