[TableGen] Add `CodeGenIntrinsicsMap` for on-demand intrinsic creation (#107100)

- Add class `CodeGenIntrinsicMap` for on-demand creation of  
  `CodeGenIntrinsic`.
- Add class `CodeGenIntrinsicContext` to capture global information
  required to build `CodeGenIntrinsic` objects.
- Adopt GlobalISel PatternParser and SearchableTableEmitter to use it.
