Option to do single precision mesh communication. (#2294)
* option to use single precision guard cell exhanges
* add missing files
* fix namespace issue
* change precision of comms to float
* ParmParse the single_precision_comms flag
* set back to real
* test
* make sure dst is filled
* nGrow -> nGrowVect
* restore float
* don't override valid cells
* single precision mesh
* whitespace
* wrap SumBoundary
* Wrap additional uses of FillBoundary.
* catch missing copies of ParallelCopy
* missing OverrideSyncs
* add wrapper for iMultifab
* fix typo
* moar typos
* typo
* strip single_precision_mesh option
* fix original copy
* update fusible syntax

* Fix: Single Precision Builds
Should not copy around data for `do_single_precision_comms`
* Docs: warpx.do_single_precision_comms
* initialize this tmp multifab to 0.0
* fix tiny profile label
* remove orig copies, they are only correct for FillBoundary
* loosen tolerance for space charge tests for single precision
* missing some setVal
* another missing setVal
* missing setVal
* add wrapper for new version of sumboundary
* add explicit cast to silence compiler warning
* add a test for single precision comms
* revert change to test precision
* add benchmark for single precision comms test
* restore tolerance I removed by mistake
* tolerance
* copyright headers
* drop tolerance for single precision tests in default analysis script
* missing python module
* bump tol again
* fix bad merge
* Apply suggestions from code review
