HLE: Slightly speed up IpcService creation

This is not a crazy speedup, we're talking fractions of a millisecond here (I had to measure in ticks; 10000000 ticks per second)

- TIPC commands are opted-into for registration since they are only used for IUserInterface, but were still attempted to be initialized for every service which spent needless time.

- Directly use GetType() instead of accessing all exported types, and Where()ing for equivalency to GetType(). This causes the logic for registration to be a lot faster.
