  -----------
  [NFC][GlobalISel] Refactor ownership of InstructionMatchers (#200798)

- Clarify that the array of InstructionMatchers in the RuleMatcher are for the roots only.
- Let RuleMatcher own all of the InstructionMatcher used for/by predicates.
They are all kept in an array in which the index of the InstructionMatcher is equal to its
InsnID, which eliminates some redundant tracking.
- Remove duplicate tracking of InsnID from RuleMatcher; InstructionMatcher does it on its own already.
