GLES2: Fix comments in previous commit that broke rendering (!)
...
Do NOT use "[vertex]" in a comment...
Kids, don't try to learn OpenGL on a production branch right before
a stable release.

GLES2: Add comments around EXT_shader_texture_lod check
...
To avoid reintroducing bugs as I did in #26928 and #26932 .
texture2DLodEXT and textureCubeLodEXT are only for the fragment shader with
https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_shader_texture_lod.txt
In the vertex shader, texture2DLod and textureCubeLod are built-in.

GLES2: Ensure extension checks for texture2DLod
...
In canvas.glsl and scene.glsl, we were using texel2DFetch from stdlib.glsl,
which uses texture2DLod. In both cases, the stdlib.glsl include came before
the define of texture2DLod.
Might fix issues for drivers that don't support GL_EXT_shader_texture_lod.

WebGL1 some changes
...
glRenderBufferStorage doesn't accept the _DEPTH_COMPONENT24_OES so I changed it to GL_DEPTH_COMPONENT16
https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/renderbufferStorage
https://www.khronos.org/registry/webgl/extensions/rejected/OES_depth24/
Enabled ext_shader_texture_lod extension. I guess it does the same like the GL_ARB_shader_texture_lod extension, but in WebGL1
https://www.khronos.org/registry/webgl/extensions/EXT_shader_texture_lod/
And last WebGL1 doesn't allow indexes not constant, so I changed it into a loop reading this:

GLES2: Define 'lowp' for OpenGL 2.1
...
Precision qualifiers are only used on OpenGL ES 2.0 and 3.0,
and while OpenGL 3.3 defines them for compatibility (but without
practical effect), they're missing from OpenGL 2.1, so we define
them to prevent compilation errors.
Fixes #24521 .

Style: Enable clang-format on GLSL shaders
...
As of clang-format 6.0.1, putting the `/* clang-format off */` hint
around our "invalid" `[vertex]` and `[shader]` statements isn't enough
to prevent a bogus indent of the next comments and first valid statement,
so we need to enclose that first valid statement in the unformatted chunk.

This commit adds a new rendering backend, GLES2, and adds a
project setting to enable it.
Currently this backend can only be used on the X11 platform,
but integrating into other platforms is planned.
