ci: workflows: upload doxygen coverage to codecov together w/ unittests

Remove codecov upload from doc build workflow and instead ensure both
test and doxygen coverage is uploaded in the same codecov.yml workflow,
this way codecov report will accurately show the consolidated coverage
for each "push" commit.
