`clang/tools/scan-build` is implemented in `perl`. However given `perl` is not mentioned as a required dependency in `GettingStarted.rst` we should make this optional. This adds a `find_package(Perl)` check to cmake and disables the `scan-build` tests when no perl executable is found. Ideally we would also check if dependent perl modules like `Hash::Util` are present on the system, but I don't see any pre-existing cmake macros to easily test this. So for now I go with a plain check for the `perl` package, at least this allows to use `cmake -DCMAKE_DISABLE_FIND_PACKAGE_Perl=ON` to manually disable `perl` and the tests.
