Implement SamplerVideoWEBGL for WEBGL_video_texture extension on desktop
WEBGL_video_texture is an extension that will improve uploading video frame to WebGL performance.
(https://www.khronos.org/registry/webgl/extensions/proposals/WEBGL_video_texture/)
This extension introduced a new texture type TEXTURE_VIDEO_IMAGE_WEBGL and a new sampler type
samplerVideoWEBGL to sample it.
In chromium implementation, TEXTURE_VIDEO_IMAGE_WEBGL maps to different native texture type
based on platform. On desktop, it maps to GL_TEXTURE2D(Currently supported). On Android, it
should map to GL_TEXTURE_EXTERNAL(TODO). SamplerVideoWEBGL needs to be mapped to sampler2D or
samplerExternalOES according to TEXTURE_VIDEO_IMAGE_WEBGL implementation.
This patch implements samplerVideoWEBGL in Angle to support WEBGL_video_texture on desktop. In
this case, samplerVideoWEBGL should map to sampler2D.

Standardize copyright notices to project style
For all "ANGLE Project" copyrights, standardize to the format specified
by the style guide. Changes:
- "Copyright (c)" and "Copyright(c)" changed to just "Copyright".
- Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1").
- Fixed a small number of files that had no copyright date using the
initial commit year from the version control history.
- Fixed one instance of copyright being "The ANGLE Project" rather than
"The ANGLE Project Authors"
These changes are applied both to the copyright of source file, and
where applicable to copyright statements that are generated by
templates.

Store symbol names as a ImmutableString
This will enable compile-time initialization of built-in symbols as
well as reducing copying strings.
Most of the code that deals with names is changed to use
ImmutableString where it makes sense to avoid conversions.
The lexer/parser now allocate const char pointers into pool memory
instead of allocating TStrings. These are then converted to
ImmutableString upon entering TParseContext.

Store unmangled function names in the AST
This makes the code simpler across the board. There are a few cases
where mangled names still need to be generated in AST traversers, but
they are outweighed by much leaner output code for all function nodes.

Remove invariant declaration in vertex shader for translation from ESSL 3.00 to GLSL <= 4.1
This is a follow-up patch of
https://chromium-review.googlesource.com/408569. This CL removes
invariant declaration in ESSL 3.00 vertex shader, such like:
"
out vec4 foo;
invariant foo;
"
This CL also adds the workarounds in libANGLE.

translator: Scope all classes with "sh".
I was seeing an odd problem with our PoolAlloc conflicting with the
glslang/Vulkan TIntermNode, so the fix was to move everything to a
separate namespace.
The bison grammars are also regenerated. No functional changes.

Reland "Remove invariant qualifier for input in fragment shader"
This relands https://chromium-review.googlesource.com/#/c/400005/.
ESSL and GLSL are not consistent on invariant matching in vertex shader
and fragment shader. See the following rules:
ESSL 1.00 - input and output must match
ESSL 3.00 - only output, inputs cannot be declared as invariant.
GLSL 1.10.59 - does not exist
GLSL 1.20.8 - input and output must match
GLSL 1.30.10 - input and output must match
GLSL 1.40.8 - input and output must match
GLSL 1.50.11 - input and output must match
GLSL 3.30.6 - input and output must match
GLSL 4.00.9 - input and output must match
GLSL 4.10.6 - input and output must match
GLSL 4.20.11 - input can omit invariant
GLSL 4.30.8 - input can omit invariant
GLSL 4.40.9 - input can omit invariant
GLSL 4.50.5 - input can omit invariant
Since GLSL 4.20, invariant qualifier description were changed to:
"
Only variables output from a shader (including those that are then input
to a subsequent shader) can be candidates for invariance. This includes
user-defined output variables and the built-in output variables. As only
outputs need be declared with invariant, an output from one shader stage
will still match an input of a subsequent stage without the input being
declared as invariant.
"
It's not very clear if input in fragment can be declared as invariant.
Mesa driver disallows use of input declared as invariant in fragment
shader, while other drivers may allow it. This CL removes invariant
declaration for input in fragment shader except AMD driver in Linux.
AMD's driver obviously contradicts the spec by forcing invariance to
match between vertex and fragment shaders.

Add an SH_GLSL_CORE_OUTPUT profile.
So we could generate shaders for Apple using core GL profile.
By switching to core profile, we still pass most WebGL conformance tests 1.0.2 on Linux, but not all, so apparently more work is needed.
However, I think it's OK to check this CL in because this output profile will be only used behind a chromium switch.
