[PATCH i-g-t v1] tests/kms_plane_scaling: Skip scalar2 downscale tests on Intel Gen14+ with specific conditions

[Naladala Ramanaidu]

Add a conditional check to skip tests involving scalar2 downscale
operations on Intel devices. This avoids running unsupported
scenarios and helps prevent potential test failures.

Bspec: 69901
