Changes in V4:
- Code
This patch disables unnecessary configs for two cases:
1. By utilizing EXTRA_FIXED_RANDCONFIG and risc-fixed-randconfig.yaml
file for randconfig builds (GitLab CI jobs).
2. By using tiny64_defconfig for non-randconfig builds.

The header is similar between Arm, PPC, and RISC-V,

Arm's nospec.h was taken as a base with updated guards:
_ASM_ARM_NOSPEC_H -> _ASM_GENERIC_NOSPEC_H
