Use packed enums for the texture types and targets, part 1
In OpenGL there are two enum "sets" used by the API that are very
similar: texture types (or bind point) and texture targets. They only
differ in that texture types have GL_TEXTURE_CUBEMAP and target have
GL_TEXTURE_CUBEMAP_[POSITIVE|NEGATIVE]_[X|Y|Z].
This is a problem because in ANGLE we use GLenum to pass around both
types of data, making it difficult to know which of type and target a
variable is.
In addition these enums are placed somewhat randomly in the space of
OpenGL enums, making it slow to have a mapping from texture types to
some data. Such a mapping is in hot-code with gl::State::mTextures.
This commit stack makes the texture types and target enums be
translated to internal packed enums right at the OpenGL entry point
and used throughout ANGLE to have type safety and performance gains.
This is the first of two commit which does the refactor for all of the
validation and stops inside gl::Context. This was the best place to
split patches without having many conversions from packed enums to GL
enums.

Support CHROMIUM_copy_texture for all formats on D3D11.
Adds a CPU readback and conversion path when the destination texture is
not renderable.

ES3: Make copy conversion set a static switch.
This removes the global std::set initialization.
