Update checks for floating point renderability.

 * Expose GL_CHROMIUM_color_buffer_float_rgb and
   GL_CHROMIUM_color_buffer_float_rgba
 * Fix many texture formats that were incorrectly checking the wrong
   extension for support or renderability.
 * Make all floating point texture extensions dynamically enableable.
