Change sksl tests to avoid SPIR-V validation errors 'in' variables without locations aren't allowed. Use uniforms instead.

Implement bitCount intrinsic on SPIR-V and Metal. This intrinsic was previously lacking a unit test, and wasn't actually implemented in Metal or SPIR-V. Fortunately it's trivial to add.
