There is this weird thing in the current tests that the linear & tiled
buffers are sized the same.
They don't need to be, compute a max area we want to check (aligned to
a tile logical size), allocate the linear buffer using that aligned
size and allocate the tiled buffer using a size aligned to the
physical tile size.

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.
