docs(simd): introduce CTX_INCLUDE_SVE_REGS build flag

This patch documents the support for the newly introduced
CTX_INCLUDE_SVE_REGS build flag. Since this build flag is influenced
by other build flags, the relevant sections have been updated with
proper guidance.

This patch also documents the SEPARATE_SIMD_SECTION build flag.
