This patch introduces Scripted Processes to lldb.
The goal, here, is to be able to attach in the debugger to fake processes
that are backed by script files (in Python, Lua, Swift, etc ...) and
inspect them statically.
Scripted Processes can be used in cooperative multithreading environments
like the XNU Kernel or other real-time operating systems, but it can
also help us improve the debugger testing infrastructure by writting
synthetic tests that simulates hard-to-reproduce process/thread states.
Although ScriptedProcess is not feature-complete at the moment, it has
basic execution capabilities and will improve in the following patches.

In order to facilitate the writting of Scripted Processes, this patch
introduces a `ScriptedProcess` python base class in the lldb module.
The base class holds the python interface with all the - abstract -
methods that need to be implemented by the inherited class but also some
methods that can be overwritten.
This patch also provides an example of a Scripted Process with the
`MyScriptedProcess` class.

The Python code generated by SWIG is compatible with both Python 2 and
Python 3. The -py3 option enables Python 2 incompatible features such as
function annotations and abstract base classes.

LLVM install component targets needs to be in the form of: install-{target}[-stripped]
I tested with:
```
cmake ... -DLLVM_ENABLE_PROJECTS="clang;lldb" -DLLVM_DISTRIBUTION_COMPONENTS="lldb;liblldb;lldb-python-scripts;" ...
DESTDIR=... ninja install-distribution
```
@JDevlieghere `finish_swig_python_scripts` is a really weird name for a distribution component, any reason that it has to be this way?

This patch is a big sed to rename the following variables:
s/PYTHON_LIBRARIES/Python3_LIBRARIES/g
s/PYTHON_INCLUDE_DIRS/Python3_INCLUDE_DIRS/g
s/PYTHON_EXECUTABLE/Python3_EXECUTABLE/g
s/PYTHON_RPATH/Python3_RPATH/g
I've also renamed the CMake module to better express its purpose and for
consistency with FindLuaAndSwig.

After moving python.swig and lua.swig into their respective
subdirectories, the relative paths in these files were out of date. This
fixes that and ensures the appropriate include paths are set in the SWIG
invocation.

Separate the CMake logic for Lua and Python to clearly distinguish
between code specific to either scripting language and the code shared
by both.
What this patch does is:
- Move Python specific code into the bindings/python subdirectory.
- Move the Lua specific code into the bindings/lua subdirectory.
- Add the _python suffix to Python specific functions/targets.
- Fix a dependency issue that would check the binding instead of
whether the scripting language is enabled.
Note that this patch also changes where the bindings are generated,
which might affect downstream projects that check them in.
