perf: add a `--clear-caches` to `perfbranchmapupdate`
This flag will help to measure the time we spend loading various cache that
support the branchmap update.
Example for an 500 000 revisions repository:
hg perfbranchmapupdate --base 'not tip' --target 'tip'
! wall 0.000860 comb 0.000000 user 0.000000 sys 0.000000 (best of 336)
hg perfbranchmapupdate --base 'not tip' --target 'tip' --clear-caches
! wall 0.029494 comb 0.030000 user 0.030000 sys 0.000000 (best of 100)
