perf: add --clear-revlog flag to branchmapload

Having the changelog index already loaded when loading the branchmap can have a
large impact on performance.

Example runs (large private repository):

hg perfbranchmapload -f base
! wall 0.116722 comb 0.120000 user 0.110000 sys 0.010000 (best of 59)
hg perfbranchmapload -f base --clear-revlogs
! wall 0.258246 comb 0.230000 user 0.220000 sys 0.010000 (best of 31)
