feat(android): modified plugin annotation format for multi-permissions and empty (auto-grant)

[carlpoole]

Allows for the following annotation formats for permissions:

Multiple permissions can be grouped within the same @Permission sub-annotation and alias.

@CapacitorPlugin(
    name = "Geolocation",
    permissions = {
        @Permission(permission = { Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION }, alias = "location")
    },
    permissionRequestCode = GeolocationPlugin.GEOLOCATION_REQUEST_PERMISSIONS
)

Permission element can be omitted to define a permission that should be auto-granted. Useful when another platform has the permission but Android does not.

@CapacitorPlugin(
    name = "Notifications",
    permissions = {
        @Permission(permission = {}, alias = "notifications")
    }
)

I'm still confused as to why this part is necessary: (perm.permission().length == 1 && perm.permission()[0].isEmpty())

It is handling this case?

@Permission(permission = {""}, alias = ...

[carlpoole]

yes or this valid definition

@Permission(permission = "", alias = ...

which on the back end translates to an array containing one empty element

Let's switch to Kotlin.
