Setting EGL_WIDTH or EGL_HEIGHT results in mFixedWidth and mFixedHeight
changing their values.

Whenever the swap chain is tested for needing a resize, surfaces with
mFixedSize are treated as if they should be resized to mFixedWidth and
mFixedHeight from their current size. This way fixed-size surfaces
can be resized - it's enough to do a couple of eglSurfaceAttrib() calls
and then either let ANGLE check surface for needing a resize in due course,
or force that by calling eglWaitNative().

Declaring HLSL outputs with SV_* semantics after the ones with
TEXCOORD* semantics makes multiview shaders that contain a flat
varying run correctly. This is a workaround for what seems to be a
bug in the DX runtime, reproducible on at least NVIDIA and Intel.

This also adds another, clearer test case for flat interpolation used
together with multiview.

This implements GL_OES_draw_texture using a few bits of new state
in the renderer and adding a code path for it in the shader, using
gl_VertexID to draw the quad backing the texture draw. This allows us
to avoid allocating a separate vertex array for the texture draw and
reuses the current shader as much as possible, plugging in to the
existing multitexturing pipeline.

- Add unit test and sample
- No new test expectations, but advertising GL_OES_draw_texture makes
the DrawTex GLES1 conformance test non-trivial and actually test
