Way to ustrip an array efficiently

Looks like there is no single way to "ustrip all values in an array, as efficiently as possible".

- `ustrip(x)`: efficient for `Array` (reinterprets), not efficient for `range` (materializes); also, deprecated
- `ustrip.(x)`: efficient for `range` of `Quantities` (keeps a range), not efficient for `range` of regular numbers or for `Array` (materializes/copies)

Would be great to have such a way!

Start by comparing the `ustrip(x)` and `ustrip.(x)` entry points for `Array`, `range`, `Quantities`, and regular numbers. Define a single approach that avoids unnecessary materialization or copying while preserving efficient ranges, then verify the behavior across those cases.
