vkr: add VKR_CONTEXT_VALIDATE_FULL

VKR_CONTEXT_VALIDATE_FULL enables all meaningful validations while
VKR_CONTEXT_VALIDATE_ON enables only API_PARAMETERS.

We would like VKR_CONTEXT_VALIDATE_ON to cover more validations, but we
also need to balance for compatibility (most apps have sporadic
validation errors) and performance.  That will be an ongoing work.
