JIT: slightly increase the inline budget (#118641)

The inline budget is set by the root method being compiled. If we inline
a large method into a small one, we sometimes run out of budget trying
to inline the large method's callees.

Increase the budget from 20 to 22 to give us a bit more breathing room.

Fixes some regressions from #114996 / #116054
