Feat: ios location precision

[Pierre-Monier]

Added getLocationAccuracy and requestTemporaryFullAccuracy methods, implemented only for iOS. Introduced a new LocationAccuracyStatus enum. Users can now check location accuracy on the iOS platform.

close #558

I have not made any changes to the permission_handler module. I’m not sure if I should add code to use the implemented feature, as it is currently only available on iOS.

Updating pubspec.yaml versions broke the CI, but this step is required in the PR checklist. Did I miss something?

• permission_handler_platform_interface/pubspec.yaml : 4.2.3 → 4.3.3
