LOG: [lldb] add cross platform test commands in Makefile.rules (#180224)

This patch adds cross platform (Darwin, Linux, Windows) commands in
`Makefile.rules` which is used to build lldb test targets.

This maps POSIX commands like `mkdir -p` to their Windows equivalent,
which allows to create cross platform `Makefile` for lldb's test
targets. This is currently not needed by any test but might become
useful later as we are working on enabling more lldb Windows tests.

This was originally done in the `swiftlang/llvm-project` fork
(https://github.com/swiftlang/llvm-project/pull/12127)
