Austin Eng b8a56af176 Rephrase Format::aspect enum as an enum class mask
Format::aspect should be a mask so that it is easier to iterate over
and test if an aspect is present.

This CL also re-exports wgpu's EnumClassBitMask helpers in dawn_native.
It also adds an EnumMaskIterator which wraps BitSetIterator to allow
iterating over the enums in an enum mask.
