Computing the working set involves running few git commands, including git diff, it can be skipped if the "Expand Sync to Working Set" option is disabled.

The working set will be computed on each `collectProjectState` call, given that this method is triggered three times per sync operation, disabling unnecessary working set computations can reduce the sync times roughly the amount of time taken by 3 git diff runs.

Currently, BlazeInfo will be computed 5 times during incremental sync, this commit introduces logic to cache it and re-use the computed value during incremental syncs.

`BlazeInfoProvider` was introduced in order to avoid changing `BlazeInfoRunner` and keep its responsibility to solely execute the info command.

Logic is guarded by `blaze.info.provider.enabled` which is disabled by default.
