This allows individual components to be better maintained following the deprecation of riscv-tools. Eliminate non-essential submodules. build-static-libfesvr.sh is no longer necessary since libfesvr.a is built as part of the riscv-isa-sim build. For simplicity, only riscv-gnu-toolchain is now pre-built instead of the entirety of riscv-tools.
