tests: riscv: Add unit tests for riscv_pmp_decode_region
This commit introduces a suite of unit tests for the `pmp_decode_region`
function using the Ztest framework. The tests validate the correct
calculation of start and end addresses for various RISC-V PMP
(Physical Memory Protection) entry configurations.
The following scenarios are covered:
- TOR (Top of Range) mode for index 0.
- TOR (Top of Range) mode for index > 0.
- NA4 (Naturally Aligned Four-byte) mode.
- NAPOT (Naturally Aligned Power-of-Two) mode.
- Default behavior for a disabled PMP entry.
These tests ensure the PMP region decoding logic is accurate across
different addressing modes.
