Fix linear to sRGB conversion functions

These functions didn't work for the whole range, causing numerical
errors. Added an explicit boundary check to fix the issue.

Without this change, we were failing these SwANGLE tests:
dEQP-GLES3.functional.fragment_ops.blend.fbo_srgb.equation_src_func_dst_func.*

I logged https://gitlab.khronos.org/Tracker/vk-gl-cts/-/issues/4133 to address the lack of coverage for sRGB values in dEQP-VK.
