Vulkan: Fix texelFetch(externalSampler) behavior
GLES expects YUV decoding to happen with texelFetch when an external
sampler is used, but texelFetch's translation (OpImageFetch) does not do
such a thing. A transformation is added to replace that with a texture
call at the right coordinate.

YUV should support on all the shader stages
* The spec requires all shader stages should support YUV. Therefore,
move YUV related functions out of the switch.
* Add a new end2end test that sampling YUV in the vertex shader.

Vulkan: Add test for __samplerExternal2DY2YEXT then swizzle
Added a correctness test
SourceYUVTextureTargetExternalRGBSampleYUVSampleWithSwizzle for applying
swizzle after sampler.
Also removed some bug workaround for VVL and drivers since they are
fixed now.

Vulkan: Fix __samplerExternal2DY2YEXTtnd combined with swizzle
Pixel camera app is hitting assertion due to swizzle applied to swizzle.
This CL adds ReswizzleYUVOpsTraverser::visitSwizzle() method and detects
there is a swizzle on YUV sampler and apply YUV swizzle first and then
original swizzle and then fold two swizzle into one.
This CL added a test to reproduce the bug.
This CL also makes ShCompileOptions in ShaderExtensionTest class a class
member instead of local variable so that subclass can modify for testing
or debugging purpose.

Vulkan: Swizzle YUV output from GL component order to vulkan
Since OpenGL and vulkan has different YUV component ordering, we need to
swizzle the component form GL to vulkan when we write YUV data to output
variable. The computation in shader will still carry out in OpenGL
order. This CL swizzles component for the YUV output variable.
