Interactively ask for package providers when computing deps for AUR package

[actionless]

otherwise, if package is not installed the first matching package provider will be used

it should be handled in the same way how it handled now for directly installing packages by their Provides field (ie pikaur -S java-runtime) when it first possible to choose the provider via [m]anual package selection and next if such choice won't be done, additional prompt will be shown to make that choice finally

[actionless]

could be reproduced with any AUR package depending on such package like java-runtime, eg minecraft-launcher
