arch-riscv: Add support for fault handling
This patch adds support for handling RISC-V faults, including tracking current and previous execution privilege, correctly switching to the privilege mode specified by CSRs, and setting/storing the PC. It also includes changes introduced by patch #9821, which disables interrupts during handling of a fault.
