feat: consistent file input behavior on android

## Feature Request

### Description

When using `` on Android, allow the user to choose what app to use (e.g. Camera or Files), unless the behavior is restricted by `accept` or `capture` attributes.

Current behavior on Android with Capacitor seems to be:
- If [`capture`](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/capture) attribute is present, and `IMAGE_CAPTURE` action is defined in `AndroidManifest.xml` then open the camera,
- Otherwise open the file browser

This differs from the behavior in Chrome for Android or Capacitor on iOS, both of which let the user choose between multiple apps when the `capture` attribute isn't set.

### Platform(s)
- Android

### Preferred Solution
Show an [app chooser](https://developer.android.com/training/basics/intents/sending#AppChooser) an Android depending on the `accept` and `capture` properties:
- If [`capture`](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/capture) attribute is present, then directly open camera
- If [`accept`](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/accept) attribute is used to only include types that aren't images, then directly open file browser
- Otherwise show an [app chooser](https://developer.android.com/training/basics/intents/sending#AppChooser), which should include at least Camera and File options


Also document that on Android it's necessary to add the following code to `AndroidManifest.xml` in order to show the camera from a file input:

```xml






```

### Alternatives

Document the differences in behavior between Android and web/iOS, as well as a suggested workaround (e,g, implementing a custom action sheet or popover with options for Camera and Files).
