Optimize angle::BitSetIterator.

Adds a new custom bitset template to handle packing as many bits as
possible into a single variable. Intelligently select the right class
depending on platform features and bit sizes.

For now, always use a packed 64-bit set on 64-bit, instead of using
a 32-bit set for smaller bitsets.
