RFR: 8272846: Move some runtime/Metaspace/elastic/ tests out of tier1

[Aleksey Shipilev]

See the bug report for more discussion. Attention @tstuefe -- is it time yet to do this?

Motivational run time improvements:


$  make run-test TEST=hotspot:tier1

# Before
real	8m9.678s
user	289m59.304s
sys	27m46.347s

# After
real	7m27.566s
user	284m4.947s
sys	27m33.724s


Additional testing:
 - [x] `tier1` no longer runs these tests
 - [x] `hotspot_tier2_runtime` runs these tests
