[PATCH i-g-t 4/4] tests/chamelium/kms_chamelium_sharpness_filter: Add adaptive sharpness chamelium filter test

Fri Oct 18 19:06:27 UTC 2024
Add new chamelium based sharpness test. Basic test is added where
we have tried comparing frame dump of unsharped and sharped image.
After, sharpness filter is applied its expected both frame dumps
will be different.
