Add R_8 GPU memory buffers format.
GpuMemoryBuffer::Format::R_8 should be used to represent textures with
only one channel, the associated image should have GL_R8/GL_R8_EXT
as internal format.
With this CL the only implementation of GpuMemoryBuffer that supports
R_8 is GLImageMemory, it expects a 4 bytes row alignment (4 is the
default value for GL_PACK_ALIGNMENT).
