[flang-rt] Pass the whole path of libflang_rt.runtime.a to linker on AIX and LoP (#131041) ...

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`.
