This PR simplifies how we enable the different fma configs for riscv: 1. Removes __LIBC_RISCV_USE_FMA define 2. Checks if __riscv_flen is defined to set LIBC_TARGET_CPU_HAS_FMA As a bonus, we enable *FMA_OPT tests for rv32, so any rv32 hardware that doesn't implement the f/d extensions is also covered by the tests.
