Split register allocation of varyings from the translator.
The translator gl::Varying struct does not need to know about register
allocation. We can put that entirely in the API library. This makes
exposing Varying variables with the new translator types cleaner.

Remove gl::Varying::elementIndex.
We only assigned to elementIndex, and never referenced the value
at any point in our code.

Stop generating duplicate vertex binaries.
We would generate multiple vertex binaries that result in the same
HLSL code, eg for vec2 and vec3 vertex attributes. Eliminate
duplicates by using the converted attribute type for testing
for matching binaries.

Move ShaderVariables to common shared source.
Also move the block layout encoding utilities to the common folder.
The combined changes allow us to include the shader and block code
into both libGLESv2 and the translator separately. This in turn
fixes the Chromium component build, where we were calling internal
translator functions directly from libGLESv2.

Fix non-square matrix vertex attributes.
When we generate an input signature for a vertex shader, we should
use the transpose of the matrix type instead of the matrix type
itself. This was breaking dEQP tests 'shaders.functions.datatypes'.

Fix matrix input attributes and formats.
We can't assume we have a simple mapping between input attribs
and shader attribs. The app specifies matrix input attribs as
several vector inputs, while the shader uses a single matrix type.
