[PATCH 05/15] docs: kdoc_files: move output symbols logic to kdoc_output

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

When writing unittests for kdoc_output, it became clear that
the logic with handles a series of KdocItem symbols from
a single file belons to kdoc_output, and not to kdoc_files.

Move the code to it.

While here, also ensure that self.config will be placed
together with set.out_style.
