cogl: Make FP16 and RGBA1010102 public features

Browse source 
Also be more strict about what we consider RGBA1010102 support. Before
GLES 3.0, using ReadPixels on a framebuffers with format RGB10_A2 was
not possible with type GL_UNSIGNED_INT_2_10_10_10_REV_EXT and thus our
code to read back pixels could fail.

Users of cogl should check those feature flags before using FP16 and
RGBA1010102 pixel formats via CoglFeatureIDs:
 * COGL_FEATURE_ID_TEXTURE_RGBA1010102
 * COGL_FEATURE_ID_TEXTURE_HALF_FLOAT
