LOG: [TableGen] Add declarations to silence gcc warning. NFC (#125892)

Add declarations of SDTypeConstraint's operator== and operator< to the
llvm namespace. These are declared as friends inside the class which
makes them part of the enclosing namespace, but gcc wants it to be more
explicit.

Fixes #125537.
