Implement ES 2,3 parts of EXT_blend_func_extended for shader translation
Exposes gl_SecondaryFragColor, glSecondaryFragData[] and
gl_MaxDualSourceDrawBuffers to GLES SL 1.0.
Relaxes rules for undefined output locations for GLES SL 3.0
and exposes gl_MaxDualSourceDrawBuffers.
If the output GL context is GL ES 2.0 or 3.0:
The emulation layer is expected to turn on EXT_blend_func_extended
if the output GL context supports it.
If the output GL context is GL:
The emulation layer is expected to turn on EXT_blend_func_extended
if the output GL context supports ARB_blend_func_extended or if GL
context is 3.2 or later.
If the source shader spec is GLES SL 2.0: The emulation layer is
expected to inspect the shader compilation output variables upon
linking. If output target is GL SL, the emulation layer should bind
color location 0, index 1 to "angle_SecondaryFragColor" if variable
"gl_SecondaryFragColorEXT" is used. Alternatively, emulation layer
should bind "angle_SecondaryFragData" to locations 0,1,2,3,..., all
color index 1, if "gl_SecondaryFragData" array is used.
(The caller can not bind the locations or specify output variables.)
If the source shader spec is GLES SL 3.0:
The emulation layer is expected to do location auto-resolve of the
the output variables that have undefined output locations that have
not been bound by the caller.
(The caller can not use gl_ built-ins, so nothing to do with those.)

Implement gl_FragDepth for GLES SL 3.0
Makes it an error to access gl_FragDepthEXT in #version 300 es shader.
TODO:
Lacks the feature to make "#extension GL_EXT_frag_depth : require" an
error for #version 300 es.

Add ability to select GLSL output type to shader translator
User can pass -x=g130, ..., -x=g450 to get output in specific GLSL
version. Passing -x=g selects GLSL compatiblity profile.

Rename translator to shader_translator and remove redundant projects.
The essl_to_hlsl and essl_to_glsl projects were exactly the same so it
doesn't make sense to keep both.
