[libc] Update riscv entrypoints to be on par with x86 (#138597)
This patch updates the riscv entrypoints with almost all functions that are currently supported on x86. I left six functions commented, as I'll send separate PRs to enable them: * poll: needs a new syscall implementation * utimes: needs a new syscall implementation * setitimer: test never finished in rv32 * getitimer: test fails in rv32 * exp10m1f: test case doesn't build but it's an easy fix * sqrtulk: needs to be implemented I also added the 16-bit fp functions, however, they are not enabled due to a cmake check in float16-macros.h. To enable 16-bit fp in riscv, we need to update the buildbots with a clang version that includes the fix from commit PR #119481
