Add unittests for linear to tiled and tiled to linear texture
conversions for Ytile. The test prints the source/output buffer
in hex format with debug flags to verify the result.
Linear to tile conversion fills the linear buffer with values
based on the OWORD index number i.e., OWORD3 will contain
all values filled as 0x03 and
OWORD3 = 0x03030303030303030303030303030303.
The Y-tile to Linear tile conversion uses a similar logic to place
the tiled values in a manner that will result in a linear buffer with
OWORDs filled according to index number as mentioned above.

The tile size calculations use a clever bit of math to make them short
and simple. We add unit tests to assert that they identically match the
tables in the PRM.

Rename the isl_aux_usage enum to clarify that it is optional on gfx125.
The new name comes from the Alchemist docs, where the feature is
referred to as "Fast Clear Optimization (FCV)".
The rename was done with this command:
git grep -l "GFX12_CCS_E" | xargs sed -ie "s/GFX12_CCS_E/FCV_CCS_E/g"

EXPECT_DEATH works by forking the process and letting the forked process
fail with an assertion. This process is evidently incredibly expensive,
taking ~30 seconds to run the whole isl_aux_info_test on a 2.8GHz
Skylake. Annoyingly all of the (expected) assertion failures also leaves
lots of messages in dmesg and potentially generates lots of coredumps.
Instead, avoid the expense of fork/exec by redefining assert() and
unreachable() in the code we're testing to return a unit-test-only
value. With this patch, the test takes ~1ms.
Also, while modifying the EXPECT_EQ() calls, reverse the arguments so
that the expected value comes first, as is intended. Otherwise gtest
failure messages don't make much sense.

Stencil CCS is slightly different from color CCS. Using a color CCS
resolve with stencil CCS doesn't do the right thing and you can't sample
from a stencil CCS image without the DepthStencilResource bit set or you
will get the wrong data. Stencil CCS also has it's own rules such as it
doesn't support fast-clear and has no partial resolve. This seems to
indicate that it should probably be its own isl_aux_usage. Now that
adding new isl_aux_usage values is pretty cheap, let's split stencil CCS
out on its own.

Provide a generic interface which manages aux resolves in ISL. The
feature differences between this and what's in iris is:
* Support for media compression. ISL_AUX_USAGE_MC behaves differently
from many other usages of CCS, so it was useful to implement this
support upfront, while designing the interfaces.
* Optimizations for full-surface writes. For example, after a
full-surface write occurs with ISL_AUX_USAGE_CCS_E in the PARTIAL_CLEAR
state, isl_aux_state_transition_write() returns COMPRESSED_NO_CLEAR
instead of COMPRESSED_CLEAR.
A performance suggestion for main-surface-invalidating/replacing writes
is given as a comment instead of adding a boolean to
isl_aux_prepare_access(). This avoids extra validation and should be
simple enough for the caller to handle.
