This commit adds exported mode to rust codegen.
When the codegen mode is exported
1. only flags with exported: true will be generated
2. the generated getter should be in a read_write format and with
default value as false, regardless the original permission and state
of the flag
This commit adds integration test for rust codegen exported mode.

Pass ownership of the ProtoParsedFlag iterator items to the Rust
codegen: this removes the need for an explicit lifetime annotation.

Consolidate the code generation sources into its own module. This is
done in preparation for when support for the new flag storage will be
added, which should also be placed in a separate module.
