Add Cranelift meeting agendas for rest of 2022. (#4156)

As per discussion today, when we have a holiday (affecting any regular
attendee), we will push the meeting by a week. This does mean we
sometimes have meetings in contiguous weeks, but given the number of
topics we usually have to discuss, erring on the side of more discussion
time (rather than just canceling) is probably not a bad thing.

For the rest of this calendar year, given an otherwise regular
biweekly-on-Mondays cadence, the holiday conflicts I am aware of are: US
Memorial Day (falls on Mon May 28, pushed meeting to Mon Jun 6); US
Labor Day (falls on Mon Sept 5, pushed to Mon Sept 12). If there are any
other holidays in the below dates, I'm happy to update further!
