This PR is to improve the driver code to build `flang-rt` path by re-using the logic and code of `compiler-rt`. 1. Moved `addFortranRuntimeLibraryPath` and `addFortranRuntimeLibs` to `ToolChain.h` and made them virtual so that they can be overridden if customization is needed. The current implementation of those two procedures is moved to `ToolChain.cpp` as the base implementation to default to. 2. Both AIX and PPCLinux now override `addFortranRuntimeLibs`. The overriding function of `addFortranRuntimeLibs` for both AIX and PPCLinux calls `getCompilerRTArgString` => `getCompilerRT` => `buildCompilerRTBasename` to get the path to `flang-rt`. This code handles `LLVM_ENABLE_PER_TARGET_RUNTIME_DIR` setting. As shown in `PPCLinux.cpp`, `FT_static` is the default. If not found, it will search and build for `FT_shared`. To differentiate `flang-rt` from `clang-rt`, a boolean flag `IsFortran` is passed to the chain of functions in order to reach `buildCompilerRTBasename`.
