Add two missing checks on render pass descriptor

Browse Source 
This patch adds two missing checks on the render pass descriptor:
1. NaN is not allowed to be a value of clearColor and clearDepth.
2. Ensure only valid values can be used as loadOp and storeOp.

This patch also adds the unit tests to ensure INFINITY is a valid
value for both clearColor and clearDepth.
