RFR: 8309899: Rename PtrQueueSet::buffer_size() [v2]

[Kim Barrett]

> Please review this renaming of PtrQueueSet::buffer_size to buffer_capacity,
> along with some associated function and variable renamings.
> 
> Despite the number of files and lines changed, it's just a name change, so
> perhaps it's trivial?
> 
> Testing:
> mach5 tier1
> 
> Note: There weren't any changes needed in Shenandoah, even though it uses the
> SATBMarkQueue stuff.
