tools/[Rust|D]: Fix the Rust and D Builds for QEMU RISC-V

This PR fixes the build for Rust Apps and D Apps on QEMU RISC-V. Previously the Rust Build selected the [incorrect Rust Target riscv64i-unknown-none-elf](https://lupyuen.github.io/articles/rust5#rust-target-is-incorrect). Now the Rust Build selects the correct Rust Target: riscv64gc-unknown-none-elf.

This PR also fixes the 32-bit RISC-V Target for D Apps. D Targets ("riscv32") are named differently from Rust Targets ("riscv32gc"), this PR restores the correct Target Names.

Note that Rust Apps won't build correctly for QEMU RISC-V 32-bit. This requires a [Rust Custom Target for riscv32gc](https://lupyuen.github.io/articles/rust4#custom-target-for-rust), which will make the NuttX Makefiles much more complicated.

Also note that `hello_d` won't build correctly for 64-bit `rv-virt:nsh64`. To date, NuttX has never supported 64-bit RISC-V for D Apps.

Modified Files:

`tools/Rust.defs`: Rename the RISC-V ISA `imafdc` to `gc` for Rust Targets

`tools/D.defs`: Exclude the RISC-V ISA for D Targets
