boards apollo4p*: Provisionally disable in twister

These boards fail to build for several samples & tests
which is blocking CI.
Let's provisionally disable them until the matter is properly
resolved.

See
#72775
#73443
#74212
for more information.

Once these issues are fixed, this change should be reverted.
