workers: add config to enable/diable workers

This adds config to disable/enable workers with default being enabled.

Test Plan:
enabled profile without updaing .hg/hgrc (the default should be to use workers) and ran
hg sprase --enable-profile <profile>.sparse
Watched in the proces explorer that hg started 12 new threads for materializing files (this is my worker.numcpus) value

Added
  [worker]
  enabled = False
to the .hg/hgrc and re ran the command. This time hg didn't spawn any new threads for matreializing of files
