KVM: riscv: selftests: Add RISCV_SBI_EXT_REG
While adding RISCV_SBI_EXT_REG(), acknowledge that some registers
have subtypes and extend __kvm_reg_id() to take a subtype field.
Then, update all macros to set the new field appropriately. The
general CSR macro gets renamed to include "GENERAL", but the other
macros, like the new RISCV_SBI_EXT_REG, just use the SINGLE subtype.
