Set proper File Origins for bundled plugins

[novotnyr]

Set proper FileOrigins for bundled plugins.

Bundled plugin classes have been incorrectly marked as FileOrigin where they should have been more specifically: as an instance of IdeFileOrigin. This resolves multiple tricky corner-cases where class origins are not reported correctly as a part of the Platform.

This is an extension of #1120.

• Introduce BundledPlugin as a FileOrigin. This corresponds to an origin of classes that belong to the same bundled plugin. This helps to discriminate between class origins in the verification rules, especially those that detect Platform invocations from Plugin invocations.
• Allow customizable file origin resolution for JARs and lib directories. These have been originally set to SingleJar or SingleLib. Treating regular plugins and bundled plugins as the same source might not be enough in some scenarios.
• Create a BundledPluginClassFinder that loads bundled plugin classes with correct origins.
• Support arbitrary origins for MainClassesLocator that has been hardwired to JARs and libs.
• Refactor PluginDetailsProviderImpl.
  • Introduce DefaultPluginDetailsProvider that supports bundled plugins with corresponding file origin resolution.
  • Replace all PluginDetailsProviderImpl references with DefaultPluginDetailsProvider as a new bundle-supporting mechanism.
