Forbid method names for built-in types

[vRallev]

Method names like

@BindsInstance public fun int(int: Int): Builder

are problematic and cause surprising errors. As @bcorso highlighted here Kapt seems to skip generating stubs for these method names. It would be great if Dagger could detect such scenarios.

There is a feature request to prevent users from using Java keywords / identifiers when using KAPT but it seems it never got enough traction to be done. https://youtrack.jetbrains.com/issue/KT-25518

The current KAPT 'strictMode' does not error out when KAPT skips generating stubs due to usage of Java keywords.

Detecting this seems decently expensive, it means we would need to validate all elements with the information of the Metadata, looking for missing ones. However, this seem like an issue KAPT could prevent more easily.

Sounds fair, feel free to close this ticket if you think there's no work needed on your side.
