mesa: add GL_RED, GL_RG support for floating point textures
Mesa supports EXT_texture_rg and OES_texture_float. This patch adds
support for using unsized enums GL_RED and GL_RG for floating point
targets and writes proper checks for internalformat when format is
GL_RED or GL_RG and type is of GL_FLOAT or GL_HALF_FLOAT.
Later, internalformat will get adjusted by adjust_for_oes_float_texture
after these checks.
v2: simplify to check vs supported enums
v3: follow the style and break out if internalFormat ok (Kenneth)
