[Drop-In] Remove `@Experimental` annotation from drop in related files

[abhishek1508]

Description

The implementation covers

• removing @ExperimentalPreviewMapboxNavigationAPI annotation from all internal and public files related to libnavui-dropin module.
• removing @ExperimentalPreviewMapboxNavigationAPI from all new components that are exposed outside libnavui-dropin module. For ex: RouteLineComponent, RouteLineComponentContract, RecenterButtonComponent etc. It shouldn't be an issue removing the experimental annotation, since these components and their respective contracts are hosted inside internal package.
• not removing @ExperimentalPreviewMapboxNavigationAPI from MapboxExtendableButton and it's usage across the SDK. This is because in some cases it's still not possible to render circular buttons with this widget. Issue was reported here
• not removing @ExperimentalPreviewMapboxNavigationAPI from any files related to ComponentInstaller and it's usage. ComponentInstaller could be subject to modifications and we need to play more with them before declaring them stable.

@abhishek1508 The changes that remove @Experimental annotation are great. However, I have a couple of questions about some other changes:

• Why are we moving and modifying ComponentInstaller classes? I think these changes are outside the scope of this PR and should be done separately.
• Why are we removing class description comments?
