runtime: call enableMetadataHugePages and its callees on the systemstack
These functions acquire the heap lock. If they're not called on the
systemstack, a stack growth could cause a self-deadlock since stack
growth may allocate memory from the page heap.
This has been a problem for a while. If this is what's plaguing the
ppc64 port right now, it's very surprising (and probably just
coincidental) that it's showing up now.
For #64050.
For #64062.
Fixes #64067.
