ParticleTileData: No Restrict in Storage (AMReX-Codes#3245)

## Summary

Remove the `restrict` qualifier from `GpuArray` members in
`ParticleTileData`. We see compilation problems with, among others Clang
14.0.6 and AppleClang, for this construct.

We expect that using `restrict` (`AMREX_RESTRICT`) on APIs as well as
aliased pointers in these arrays before access should be sufficient to
prevent that the compiler thinks that individual arrays alias each other
in hot loops.

## Additional background

- WarpX build regressions since 23.03, e.g.,
  - conda-forge/warpx-feedstock#63
  - conda-forge/warpx-feedstock#64
  - BLAST-WarpX/warpx#3817
- independently, about to be remove in
AMReX-Codes#2878
