perf(rtp): reduce rtp scans (#24191)

Browse Source 
* perf(rtp): reduce rtp scans

Problem:
  Scanning the filesystem is expensive and particularly affects
  startuptime.

Solution:
  Reduce the amount of redundant directory scans by relying less on glob
  patterns and handle vim and lua sourcing lower down.
