Vulkan: Rotate gl_PointCoord for Android pre-rotation
This extends the current y-flip that's done for gl_PointCoord.
Now, gl_PointCoord is rotated and then flips both the x and y-axis
(similar to gl_FragCoord). The tests used to reproduce the
problem and the fix are:
angle_deqp_gles2_tests --local-output --gtest_filter=dEQP.GLES2/functional_shaders_builtin_variable_pointcoord* --use-angle=vulkan
angle_end2end_tests --local-output --gtest_filter=*GLSLTest.PointCoordConsistency*Vulkan*

Translator: Allow tree validation in children of TCompiler
This is to be able to perform validation inside TranslatorVulkan, even
if it's through ASSERTs.
Additionally, every transformation is changed such that they do their
validation themselves. TIntermTraverser::updateTree() performs the
validation, which indirectly validates many of three tree
transformations. Some of the more ancient transformations that don't
use this function directly call TCompiler::validateAST.

Vulkan: dFdy is incorrect when the framebuffer is flipped
To account for framebuffer flipping, `dFdy()` expressions
must be changed to:
dFdy() * ANGLEUniforms.viewportYScale
Bug: angleproject:3487
Test: dEQP-GLES3.functional.shaders.derivate.dfdy.*
