The ELF notes compiled in C were placed in a section with the wrong type (SHT_PROGBITS instead of SHT_NOTE). Previously, sed was used on the generated assembly to rewrite the section type. Instead, write the notes in assembly which permits setting the correct section type directly. While here, move inline assembly entry points out of C and into assembly for aarch64, arm, and riscv.
