[lldb] add missed handling for new BTFTagAttributed type

Commit 3251ba2 ("[Attr] Fix a btf_type_tag AST generation")
added a new type BTFTagAttributedType to the clang AST type
system. There are a few places in lldb needed to handle this type
similar to Attributed type to avoid compilation warning/error
when 'switch' is used to enumerate all types.
