config.nims: Support Nim Apps for RISC-V 32-bit and 64-bit

Browse Source 
NuttX Build fails when it compiles `examples/hello_nim` for RISC-V (32-bit and 64-bit). That's because the Nim Config Script `config.nims` couldn't identify the Nim Target Platform: `riscv32` or `riscv64`.

This PR fixes `config.nims` so that Nim Compiler correctly derives the Nim Target Platform (`riscv32` or `riscv64`), by searching NuttX `.config` for `CONFIG_ARCH_FAMILY=rv32` or `rv64`.

This logic is slightly different from the Nim Targets `arm` and `arm64`, which are currently derived from `CONFIG_ARCH=arm` and `arm64`.

`config.nims` is explained in this article: https://lupyuen.github.io/articles/nim#inside-nim-on-nuttx
