[igt-dev] [PATCH i-g-t] tests/gem_ccs: Remove inplace subtests

[Karolina Stolarek <karolina.stolarek@intel.com>]

block-copy-inplace and block-multicopy-inplace attempt to
decompress and detile in place, that is the destination surface
is the mid surface. When working in full resolve mode of operation,
the tiling format has to be the same for source and destination
surfaces. We can't use different tiling formats, which defeats the
purpose of these tests.

Remove the tests where we try to reuse the mid surface. Remove
references to igt_hang_t, as without inplace subtests we expect
to see no GPU hangs.
