[base] inline mconcat

vdukhovni requested to merge trac-vdukhovni/ghc:inline-mconcat-9.2 into ghc-9.2

This has already been merged into 8.10, and 9.0. This MR forward-ports it to 9.2, though it is also in effect a partial backport of the pending !4890 (closed), where we are still waiting to resolve the performance impact of the other changes.

!5301 (merged) appears to have merged this change, but did not in fact. So reopening to try to get it actually merged.
