[PATCH i-g-t v3 0/3] Move backlight read, write to lib

[Santhosh Reddy Guddati]

Move backlight read and backlight write functions to library and rename
the function as igt_backlight_read and igt_backlight_write.

changes include:

Moving the backlight read and write functions to the library.
Renaming the functions to `igt_backlight_read` and `igt_backlight_write`.
Updating the existing `kms_pm_backlight` to use the newly moved functions.
Adding a new scenario in `kms_hdr` to manipulate brightness while in HDR 
using the newly moved functions.
