riscv: Add STACKPROTECTOR supported
The -fstack-protector & -fstack-protector-strong features are from
gcc. The patch only add basic kernel support to stack-protector
feature and some arch could have its own solution such as
ARM64_PTR_AUTH.
After enabling STACKPROTECTOR and STACKPROTECTOR_STRONG, the .text
size is expanded from 0x7de066 to 0x81fb32 (only 5%) to add canary
checking code.
