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
