[PATCH i-g-t 4/6] lib/igt_kms: Export get_max_pipe_hdisplay as public helper

[Kunal Joshi <kunal1.joshi@intel.com>]

Rename the static get_max_pipe_hdisplay to igt_get_max_pipe_hdisplay
and export it as a public API. This function returns the maximum
hdisplay a single pipe can drive. Tests like basic-max-non-joiner
need this value to distinguish outputs that can reach the single-pipe
boundary from those that cannot
