review and implement transform functionals in dev

[wyli]

Is your feature request related to a problem? Please describe.
part of #4855

this is to track the progress of implementing transform functionals from the prototype defined in #5860, for logically three parts

• minor utility enhancements in
  • monai.data.metatensor (5991 add utility enhancements for lazy resampling #6017)
  • monai.transforms.lazy.utils (5991 add utility enhancements for lazy resampling #6017)
  • monai.transforms.transform (5991 add utility enhancements for lazy resampling #6017)
• crop and pad transforms with unit tests (monai.transforms.croppad)
  • crop array/dict add crop transforms with unit tests for lazy resampling #6068
  • pad array/dict add pad transforms with unit tests for lazy resampling #6031
  • remaining transforms add remaining crop transforms with unit tests for lazy resampling #6083
• spatial transforms with unit tests (monai.transforms.spatial)
  • spatial_resample 5991 Enable lazy resampling for SpatialResample #6060
  • the other spatial transforms 5991 Support more spatial transforms to use lazy resampling #6080

monai.data.dataset, monai.transforms.compose changes require more discussions and are not within the scope of this feature request.
please feel free to raise issues, and split them into subtasks if needed cc @yiheng-wang-nv @KumoLiu @Nic-Ma

Hi @wyli , @KumoLiu ,
FYI: I think that the modifications of minor utility enhancements is not very complicate relatively, therefore I will start on this part first.

Update: @KumoLiu already started working on crop transforms, thus I will focus on spatial transforms.
The class SpatialResample is a base transform, I will add its related code and unit tests first with a PR soon.
