Allow the risc-v TUNE_FEATURES to select specific ISA (kconfig) selections
in the kernel config via config fragments selected by KERNEL_FEATURES.
This allows the following items to be selected dynamically:
CONFIG_ARCH_RV32I
CONFIG_ARCH_RV64I
CONFIG_FPU
CONFIG_RISCV_ISA_C
CONFIG_RISCV_ISA_V
CONFIG_RISCV_ISA_ZBB
CONFIG_RISCV_ISA_ZICBOM
CONFIG_RISCV_ISA_ZICBOZ
CONFIG_TOOLCHAIN_NEEDS_EXPLICIT_ZICSR_ZIFENCEI
Note: Some ISA options, such as CONFIG_RISCV_ISA_C may be reenabled by other
options such as CONFIG_EFI. This is properly reported by the configuration
tooling.
