The pattern of gen context, share context, free context, then allocate
a shared GL object in the second context would cause a use-after-free
of the ContextImpl as a GLFactory. Fix this by passing the factory
as a parameter to the resource manager allocation methods instead of
storing the factory pointer. This allows the same ResourceManager to
work with separate Context implementations, which will work with
non-virtual contexts.

According to GLES 3.0.4 section 3.8.10, GenerateMipmap should generate
levels based on the base level, and generate them at most up to the
max level. Levels outside the base/max level range should be unchanged
by GenerateMipmap.

The Texture class is fixed so that the image descs are set only for
the changed mipmap range when GenerateMipmap is called.

The D3D backend is fixed so that mipmap generation is correctly
started from the base level instead of level 0, and making sure that
mipmaps are generated only up to the max level. Generating mipmaps for
array textures is also fixed for cases where the base level depth >=
max(width, height) * 2.

The GL backend is fixed to sync texture state before GenerateMipmap is
called, so that base level and max level are set correctly in the
driver.

The GenerateMipmap entry point is refactored so that it has a separate
validation function and a context function which does the work.
Validation for out-of-range base levels is added.

New tests are added to verify the functionality. One corner case in
the tests fails on NVIDIA GL drivers likely due to a driver bug -
similar rules for GenerateMipmap are found from newer GLES specs and
also OpenGL specs (checked versions 3.3 and 4.4).

The code didn't previously take base level properly into account
when determining how many levels to check when checking for texture
completeness.

The code is refactored so that the "q" value in spec, that is the
maximum mipmap level for determining completeness, can be queried from
TextureState. This value is used now for checking completeness.

This requires moving ImageDescs under TextureState. Functions that
operate on the ImageDesc array are also moved from Texture to
TextureState. TextureState members are also renamed to start with the
"m" prefix and made private.

Also handle levels outside the base/max level range consistently in
eglCreateImageKHR validation. We interpret the spec so that if the
level used for the EGL image is not a part of the texture levels that
affect texture completeness, an error is generated.
