BaseTools/tools_def: Add CLANGDWARF support for RISC-V

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4478

Add tools_def definitions to support CLANGDWARF toolchain
for RISC-V. This uses clang and the llvm LLD linker. This
helps people by not requiring to install multiple
cross compilers for different architectures.
