riscv: Rework exception handling

Browse Source 
Remove _CPU_ISR_install_raw_handler() and _CPU_ISR_install_vector()
functions.  Applications can install an exception handler via the fatal
error handler to handle synchronous exceptions.

Handle interrupt exceptions via _RISCV_Interrupt_dispatch() which must
be provided by the BSP.

Update #3433.
