[llvm] Add llvm-profgen to the list of toolchain tools (PR #120106)

[Tim Creech via llvm-commits]

https://github.com/tcreech-intel created https://github.com/llvm/llvm-project/pull/120106

This tool is used for SPGO and is invoked directly by users as described in the Clang User's Manual[^1].

This change will include llvm-profgen in installations configured with LLVM_INSTALL_TOOLCHAIN_ONLY, such as those provided by LLVM's executable Windows installers. This is useful now that LLVM can perform SPGO on Windows.
