Yong Cong Sin 033804e266 arch: riscv: support CONFIG_USERSPACE in CONFIG_RISCV_CURRENT_VIA_GP 
Reset the the `gp` register to `_kernel->cpus[i].current` when
`CONFIG_USERSPACE` is enabled on exception to keep it sane.

Updated the testcase to test both `CONFIG_RISCV_GP` and
`CONFIG_RISCV_CURRENT_VIA_GP`.
