rtems: Add get/set interrupt priorities

Browse Source 
Add directives to get and set the priority of an interrupt vector.

Implement the directives for the following BSP families:

* arm/lpc24xx
* arm/lpc32xx
* powerpc/mpc55xxevb
* powerpc/qoriq

Implement the directives for the following interrupt controllers:

* GICv2 and GICv3 (arm and aarch64)
* NVIC (arm)
* PLIC (riscv)

Update #5002.
