[lld-macho] Category Merging: Detect correct class language for classes with aliased symbols (#97454)
Currently we rely on detecting the source language of a class by the name of the symbol pointing to it. This generally works, but there are scenarios where Swift generates both an ObjC name and a Swift name for the symbol - by aliasing the ObjC name to the Swift name, as follows: ``` .globl _OBJC_CLASS_$__TtC11MyTestClass11MyTestClass .private_extern _OBJC_CLASS_$__TtC11MyTestClass11MyTestClass .set _OBJC_CLASS_$__TtC11MyTestClass11MyTestClass, _$s11MyTestClassAACN ``` So to correctly detect the source language in all cases, we need to handle scenarios where both an ObjC symbol and a Swift symbol is defined for a class - in this case the symbol is always a Swift class.
