st/mesa: Set gl_config.floatMode based on color_format

Sets the float color component type in st_visual_to_context_mode()
ensuring float color values are not clamped.
Fixes dEQP-EGL.functional.wide_color.window_fp16_default_colorspace on
asahi, iris and most likely every other driver having it marked as fail
or flake.

Closes: mesa/mesa#9276
