go/internal/gcimporter: add "bundled" export data formats

Export data is self-contained, which is convenient for ensuring the
compiler only needs to open export data files directly referenced in
source file import declarations. But it does have a consequence that
export data files can redundantly encode information.

This CL adds a new "bundled" export data format that allows encoding
multiple complete packages together so they can share transitive
declarations. This is intended to be useful for storing a compilation
unit's source files along with any export data they depend upon for
efficient re-type-checking and analysis later.
