[lldb][NFC] Remove GetASTContext call in ClangDeclVendor

Instead of returning NamedDecls and then calling GetASTContext
to find back the ClangASTContext we used can just implement the
FindDecl variant that returns CompilerDecls (and implement the
other function by throwing away the ClangASTContext part of the
compiler decl).
