[lldb] Fix crash in SymbolFileCTF::ParseFunctions (#89845)

Make SymbolFileCTF::ParseFunctions resilient against not being able to
resolve the argument or return type of a function. ResolveTypeUID can
fail for a variety of reasons so we should always check its result.

The type that caused the crash was `_Bool` which we didn't recognize
as a basic type. This commit also fixes the underlying issue and adds
a test.
