Due to CMake cache, find_package in FindLuaAndSwig.cmake
will be ignored. This commit adds EXACT and REQUIRED flags
to it and removes find_package in Lua ScriptInterpreter.

Bump the required SWIG version to 3. If my memory serves me well we last
bumped the required SWIG version to 2 for Python 3. At that time SWIG 3
had already been around for a while so everyone I know was already using
that.
It appears that SWIG 3 is the only version that officially supports
C++11 which we're using in the typemap. SWIG 3 was released in 2014 so I
think it's reasonable to make that the minimum required version.

Summary:
The purpose of this patch is to make identifying missing dependencies clearer to the user.
`find_package` will report if a package is not found, that output, combined with the exiting
status message, is clearer than not having the additional verbosity.
If the SWIG dependency is required {LLDB_ENABLE_PYTHON, LLDB_ENABLE_LUA}
and SWIG is not available, fail the configuration step. Terminate the
configure early rather than later with a clear error message.
We could possibly modify:
`llvm-project/lldb/cmake/modules/FindPythonInterpAndLibs.cmake`
However, the patch here seems clear in my opinion.

Just like Python, Lua should only be auto-enabled if SWIG is found as
well. This moves the logic of finding SWIG and Lua as a whole into a new
CMake package.
