branchmap: build the revbranchcache._namesreverse() only when required

On big repositories with a lot of named branches and that also increasing over
time, building of this dict can be expensive and shows up in profile.

For our internal repository, this saves ~0.05 seconds.

Thanks to Yuya for suggesting using util.propertycache() and
util.clearcachedproperty().
