Specify particle precision (#3065)

* Add precision to printed PIC parameters

* Added WarpX_PARTICLE_PRECISION as a build option

* Update types to ParticleReal

* Updated libwarpx to inject particles with correct ParticleReal type

* Fix syntax error

* Add logic to avoid duplicate definitions

* Use correct ParticleReal type in add_particles

* Cleaned up code, addressed comments

* Update Python/pywarpx/_libwarpx.py

* Removed redundant functions, fixed some typing

* Modified template functions

* Cast d_w to Real

* Fixed failing tests

* Cast types to be consistent

* removed in-tree-build from pip command

* Added GPU device macros to PDim3 methods

* rerun tests

* Removed unecessary casting, update calls to use PDim3 instead of XDim3

* Refactored comments

* Added mcc fields double precision, particles single precision test

* Updated casting and formatting

* Removed cast, updated declaration
