Add Capabilities::ATOMIC_COMPARE_EXCHANGE_WEAK.

We haven't finished implementing WGSL's `atomicCompareExchangeWeak` on
all platforms (#1413). It's valuable to have some configuration of
validation that guarantees backends will succeed, and adding a
`Capabilities` bit that is included by default but can be turned off
accomplishes that.
