anv/xe2+: Align push constant ranges to GRF boundaries.

This fixes corruption of push constants on Xe2 due to a mismatch in
the uniform layout implemented by the compiler and assumed by the
driver.  To fix it we need to align the push constant ranges computed
by the Vulkan driver to a multiple of the GRF size of the platform.
