LOG: [lldb][NFC] Rename TypeSystemClangForExpressions to ScratchTypeSystemClang

We keep referring to the single object created by this class as
'scratch AST/Context/TypeSystem' so at this point we might as well rename the
class. It's also not involved at all in expression evaluation, so the
'ForExpressions' prefix is a bit misleading.

Added: 
    

Modified: 
    lldb/source/Plugins/TypeSystem/Clang/TypeSystemClang.cpp
    lldb/source/Plugins/TypeSystem/Clang/TypeSystemClang.h

Removed:
