Subject: qdoc: Ensure .qhp file is generated for all modules

When run in single-exec mode, QDoc constructs only one instance
of HelpProjectWriter, even though it generates documentation for
multiple modules in one go.

This change adds a reset() function for the help project writer,
allowing new parameters to be passed to the existing writer
instance, thus ensuring that all .qhp files are correctly
generated.

Task-number: QTBUG-43815
Change-Id: I1d1c9f713eb5f574a6f8e56616cf5f61bb3e8ff8
