Reason for revert: default uniform initialization was incomplete

This change has the following fixes:
    1. Add missing default uniform initialization when loading
       program binaries.
    2. Re-enable OES Program Binary capabilities for Vulkan.
    3. Added two angle end2end test,
       - ProgramBinaryES3Test.BinaryWithLargeUniformCount
         uses several uniforms across the vertex and fragment
	 shaders.
       - ProgramBinaryES3Test.ActiveUniformShader tests
         the difference between uniform static and active use
