  target/microblaze: Add use-non-secure property

This property is used to control the security of the following interfaces
on MicroBlaze:
M_AXI_DP - data interface
M_AXI_IP - instruction interface
M_AXI_DC - dcache interface
M_AXI_IC - icache interface

It works by enabling or disabling the use of the non_secure[3:0] signals.

Interfaces and their corresponding values are taken from:
https://www.xilinx.com/support/documentation/sw_manuals/xilinx2020_2/ug984-vivado-microblaze-ref.pdf
page 153.

  target/microblaze: use MMUAccessType instead of int in mmu_translate

Using MMUAccessType makes it more clear what the variable's use is.
No functional change.

  target/microblaze: Add security attributes on memory transactions

Using the cfg.use_non_secure bitfield and the MMU access type, we can determine
if the access should be secure or not.
