Handle dependencies with export_generated_headers

Browse source 
This sets up the proper dependencies within Soong by adding the imported
dependencies into GeneratedHeaders, and re-exporting them as necessary.
It also exports them to Make using the new LOCAL_EXPORT_C_INCLUDE_DEPS.

Bug: 31742855
Test: Inspection, build hardware/interfaces (pending)
