[clang][Sema] Don't issue -Wcast-function-type-mismatch for enums with a matching underlying type (#87793)
Enums are passed as their underlying integral type so they're ABI compatible if the size matches.
Useful with C APIs that pass user-controlled values to callbacks that can be made type safe by using enumerations (e.g. GStreamer).
Discovered internally in some code after 999d4f840777bf8de26d45947192aa0728edc0fb.

[clang] move -Wcast-function-type under -Wextra (#77178)
The -Wcast-fuction-type-strict has been moved under dignstic group
-Wextra.
Edited the test cases for -Wcast-fuction-type-strict and
-Wcast-fuction-type in Sema an SemaCXX.
Added a new test case which include a functionality that was already in
the -Wextra group, i.e -Wignored-qualifiers with
-Wcast-fuction-type-strict.
Fixes: #76872

[Clang][Sema] Add -Wcast-function-type-strict
Clang supports indirect call Control-Flow Integrity (CFI) sanitizers
(e.g. -fsanitize=cfi-icall), which enforce an exact type match between
a function pointer and the target function. Unfortunately, Clang
doesn't provide diagnostics that would help developers avoid function
type casts that lead to runtime CFI failures. -Wcast-function-type,
while helpful, only warns about ABI incompatibility, which isn't
sufficient with CFI.
Add -Wcast-function-type-strict, which checks for a strict type
compatibility in function type casts and helps warn about casts that
can potentially lead to CFI failures.
