Cairo defaults to using a blended fill, so when IGT tries to paint on
top of a framebuffer in these tests with an alpha less than 1.0 the
previous framebuffer contents will still be present underneath.
On amdgpu this is an issue because the framebuffer is created in
an unitialized state and can have contents from previous tests
still within memory.
This patch explicitly sets the cairo filling operator to SOURCE to
overwrite the contents when performing fills with alpha < 1.0 in
this test.
It also fixes the creation of the transparent FB. My guess as for why
this test previously passed on i915 is because the primary FB was
also black, so the CRC would match even if the black overlay plane
was partially transparent.

Remaining tests that have been overlooked and don't need any
invasive changes to limit the skipping to only the relevant parts.
v2: [A rebase gone wrong]
v3: Move the misplaced hunk to the right patch (Antonio).
v4: Rebase, kms_content_protection is new.
v5: Rebase - need to adjust kms_lease.c too.

This will fix the -EIO from trying to start CRC on a disabled pipe.

Add a few tests to test various blending modes.
Some of the tests will skip if pixel mode alpha cannot be enabled
with plane alpha at the same time. This is for mali-dp. I didn't
test on that platform, but tested with the same check on i915.
The tests won't pass i915 on pre-gen11 hw. i915 has small rounding
errors with 0xff and 0x00 alpha, which gives CRC mismatches.
Changes since v1:
- Send the correct version, with the skips for mali-dp in place.
