  [NFC][TableGen] Reorganize GlobalISelMatchTable.h

This file was a bit of a kitchen sink, and the implementation of the
match table is sufficiently difficult to get comfortable with already.
I spent the past few weeks looking at it, finding improvements, etc. and
I think a nice way to make it a bit easier to approach is to split up
the file a bit so that the main implementation (Matchers.h/.cpp) only
contains the code pertaining to the Matchers (RuleMatchers, Preds, etc.).

We now have 3 files:

- One for type (LLT) related utilities.
- One for the MatchTable emission logic, which is generic and should not
  be tied to any specific implementation. It just has the tools to emit
  the opcodes for the table.
- One for the entire Matcher system, including PredicateMatchers and so on.
