Fixes issue on MacOS arm chip with type detection

[Hsilgos]

Closes #127

[MisterGC]

Thanks @Hsilgos for the fix and the detailed write-up in #127! I could reproduce the problem on an arm64 Mac, and your change fixes it.

To get it into the 1.3 release, I've pushed two small commits to your branch and moved the PR to release/1.3:

• The name comparison now only runs where it's needed: libc++ on arm64 Apple. Everywhere else, isType() uses the plain == as before. Without that limit, two different types with the same name (for example namespace { struct Foo {}; } in two source files) were treated as the same type, also on Linux.
• A test for that case: AnyTest.sameNamedAnonymousTypes. It's skipped on arm64 Apple, where comparing names can't tell these types apart; the comment in Any.h mentions this.
• Housekeeping: the missing #include <cstring> and the shifted clang-tidy suppression lines.

On macOS and iOS arm64 everything works exactly as with your original change. Thanks again!
