powershell.ps1: Add str, int, float types and ignore $null values (#21377)

Browse source 
* powershell.ps1: Add str type and ignore $null values

Changes include:
- New "str" type support using -type "str"
- Ensure that $null values are retained (for bool and str types)
  (Note: $null means unspecified value for parameters)
- Some minor cosmetic changes

* Also add -type "int" and -type "float"

No modules require this at the moment though.
