ANGLE would previously treat a texture as incomplete whenever its base
level was above 0. This was because the base level wasn't being taken
into account correctly when determining what size the image at a specific
mip level should be. Fix this by taking the base level into account when
determining the expected size.

On some GL driver/window system combinations the default framebuffer may
do SRGB conversion, which affects the values written there by draw

some Intel systems. For this reason, use an FBO with a known format
instead in the texture end2end tests.

This enables turning on most TextureTest cases on the OpenGL backend.

The test deliberately tries to render a scene using an invalid texture.
ANGLE rendered this correctly, but when it bound the dummy 1x1 black texture
that's used instead of invalid textures, it didn't bind a sampler state. This meant
that D3D had no pixel shader samplers bound, and outputted a debug warning.

Also, technically the test should have been setting GL_UNPACK_ALIGNMENT=1,
but that wasn't impacting the result of the test.

This removes the cube map setup and the draw scale parameter from the
tests that don't need them, and reuses the code for setting up the window
and the shader program for most of the texture tests. The tests are now
structured as follows:

TexCoordDrawTest: Test class that sets up a shader program for drawing
with texture coordinates. Vertex shader source can be overridden in
subclasses, and fragment shader source must be specified in subclasses.

Texture2DTest: Inherits TexCoordDrawTest, sets up a 2D texture and a
shader for drawing from it.

Texture2DTestWithDrawScale: Inherits Texture2DTest, adding a scale
parameter that scales the quad that gets drawn.

TextureCubeTest: Inherits TexCoordDrawTest, sets up a cube map and a 2D
texture and a shader for drawing from them.

Texture2DArrayTestES3: Inherits TexCoordDrawTest. Reserves a texture ID
and sets up an ESSL3 shader for drawing from a 2D texture array.

Also add a few comments about where things being tested are specified.

Also, ANGLETest::drawQuad parameter names are renamed to make their
meaning clearer. The parameters affect the vertex shader attribute
values, which the shader may use for other things besides setting the
vertex position.

Since EXT_color_buffer_half_float requires more format support (e.g.
R16F, RG16F, RGB16F) than OES_texture_half_float, it's possible for an
implementation to support one extension and not the other. D3D11 Feature
Level 9_3 does this.
