Remove external packages search from file base declaration provider

External package should be found because of proper module configuration
-- Remove unused
Store connection between files and lazy package fragment descriptor

LazyPackageDescriptor objects are going to be used as input for light class

and files in binding context.
Using lazy resolve when building light classes
Force-resolve only relevant declarations
Forced resolution of all contents enhanced
When building light classes don't resolve irrelevant declarations in the same package
