Subject: Change _libwarpx.py functions to LibWarpX class methods (#2696)

* Initial attempt at moving function into LibWarpX

* Bugfix - undefined structs in get_particle_theta

This is untested, identified by IDE/visual inspection only

* Unify newlines

* Delete libwarpx.clight (duplicated picmi.py)

See picmi.constants.c

* Change function descriptive comment to docstring

Also remove extra newline in __init__ beginning.

* Replace pywarpx/_libwarpx calls appropriately

* Fix atexit register of finalize function

* Reorder WarpX.py imports for pre-commit

* Use picmi.Simulation.extension = libwarpx alias

This will hopefully preempt user script changes if we restructure things
to allow multiple WarpX runs to be done within a single Python script.

* Fix libwarpx ref in WarpX.getProbLo/getProbHi

* Update get_particle_boundary_buffer doc reference
