[Feature Request] Dynamic Defaults/Overrides Providers

[SkyaTura]

Problem to solve

Currently, it is only possible to provide static default overrides when using v-defaults-provider

Proposed solution

Allow to receive a factory of defaults as a possible input.

That could provide a callback that receives context about the object being injected and something useful surroundieg context as well.

For instance, every button that has a href will also prepend an icon by default.

A new component v-overrides-provider could also be created, allowing, for instance, to check all input labels if there is a valid i18n language entry and replacing it if applicable.
