[llvm] install tools in tools/llvm (#14399)

* [llvm] install tools in tools/llvm

* remove the giant commented out block of code

* update port-version

* hopefully fix the port?

There are still some issues, namely that the python scripts and DLLs that are copied into `tools/llvm`
are not considered to be "installed by llvm", and thus are not removed when llvm is removed

* format!

* apparently REGEX REPLACE fails if a thing doesn't match

* fix LLVM_REMOVE_EXTENSION_REGEX on windows

* actually read the cmake regex docs...

* fix the name of the variable

* turns out CMAKE_MATCH_1 is the one I want

* need to update VERSION for new policy

* stop removing debug/bin

* fix faulty merge
