RFR: 8292068: Convert ModuleEntryTable into ResourceHashtable [v3]

[Coleen Phillimore]

> Converted the ModuleEntryTable to use ResourceHashtable.
> Ran tiers 1-7.  Also ran performance tests with this and other changes with no performance difference, although the footprint of this should be better.

Coleen Phillimore has updated the pull request incrementally with one additional commit since the last revision:

  Revert modules_do() assert Module_lock and taking it for process_module_table.  This should be fixed separately.
