This patch introduces a new scripting affordance in lldb:
`ScriptedFrame`.
This allows user to produce mock stackframes in scripted threads and
scripted processes from a python script.
With this change, StackFrame can be synthetized from different sources:
- Either from a dictionary containing a load address, and a frame index,
which is the legacy way.
- Or by creating a ScriptedFrame python object.
One particularity of synthezising stackframes from the ScriptedFrame
python object, is that these frame have an optional PC, meaning that
they don't have a report a valid PC and they can act as shells that just
contain static information, like the frame function name, the list of
variables or registers, etc. It can also provide a symbol context.

This patch adds support to the haswell sub-architecture (x86_64h) to
scripted processes.

The newly added
test/API/functionalities/scripted_process_empty_memory_region/dummy_scripted_process.py
imports
examples/python/templates/scripted_process.py
which only has register definitions for x86_64 and arm64.
Only run this test on those two architectures for now.
This patch adds the documentation for a subset of scripting extensions
such as scripted process, scripted thread, operating system threads &
scritped thread plans to the lldb website.

This patch introduces an `OperatingSystem` base implementation in the
`lldb` python module to make it easier for lldb users to write their own
implementation.
The `OperatingSystem` base implementation is derived itself from the
`ScriptedThread` base implementation since they share some common grounds.
To achieve that, this patch makes changes to the `ScriptedThread`
initializer since it gets called by the `OperatingSystem` initializer.
I also took the opportunity to document the `OperatingSystem` base
class and methods.

This patch moves the template files for the various scripting
affordances to a separate directory.
This is a preparatory work for upcoming improvements and consolidations
to other scripting affordances.
