GLES1: caps: Use GLES3 spec shader compiler

If we attempt to compile the GLES1 emulation shader when the client
version is 1, we use the webgl 1 / GLES2 spec, not the GLES3 spec that
we use for GLES1 emulation.

This CL adds a case in Compiler.cpp for ES 1 contexts to use the higher
spec shader compiler.
