As discussed previously, let's use the new macro
`LIBUNWIND_PTRAUTH_CALLS_AND_RETURNS` defined as follows everywhere instead of
`__has_include(<ptrauth.h>)`, `__has_feature(ptrauth_calls)`,
`__has_feature(ptrauth_returns)`, `__has_extension(ptrauth_qualifier)`, etc:
```
#if __has_feature(ptrauth_calls) && __has_feature(ptrauth_returns)
#define LIBUNWIND_PTRAUTH_CALLS_AND_RETURNS
#elif __has_feature(ptrauth_calls) || __has_feature(ptrauth_returns)
#error "Either both or none of ptrauth_calls and ptrauth_returns is allowed to
be enabled"
#endif
```
See proposed fix in commit 644405b56cfa59dd3787119182df087dff6e756c in my
branch
https://github.com/kovdan01/llvm-project/commits/pointer-authenticated-unwinding-2025-09-22-with-fixes/.
I think this should be done in scope of this PR.
