Improve current multisampled renderbuffer/texture support This is split off from a change to implement multisampled textures for the Vulkan back-end, and will come before that change. The changes include: - Make a common utility rx::GetSamplePosition() function. D3D11 and Vulkan use the same standard sample positions/locations for 1, 2, 4, 8, and 16 samples. The D3D11 back-end has a utility function for this, which is being moved to a common location--for use by both the D3D11 and Vulkan back-ends. - Texture::setStorageMultisample() handles converting the "requested number of samples" to the actual number of samples used (e.g. converting 3 to 4), supported by the underlying back-end). The actual number used is stored in gl::TextureState::mImageDescs, for use by other GLES commands. - Change some end2end tests to not make assumptions about the supported number of samples, but to properly query what is supported.
