This eliminates any dynamic allocation for hash tables that are never used.
This helps SkPicture, where some tables (SkPaint) are almost always used, but
some rarely (SkMatrix) or never (SkRegion).
This also removes the (as yet unimportant) ability for the hash table to
shrink. This makes resizing harder to reason about, so I'd like to leave it
out until we see a need.

- add validate()
- make add() and remove() strict
- fill in maybeShrink()
- make grow and shrink thresholds configurable.
- fix issue where we were getting filled with deleted items - we need to count them as occupied when determining if we should grow
