DOC: Fix typos

Typos in CMakeLists.txt (qmlrpc -> qxmlrpc) was introduced
in 4f6262c (DOC: Add comment documenting why the "eventbus" plugin is
disabled with Qt5) and identified while inspecting the file.

Remaining of typos were identified and/or fixed using codespell using the
following script:

```
python3 -m venv /tmp/codespell
source /tmp/codespell-venv/bin/activate
pip install codespell

echo "comunication

codespell -I /tmp/.codespellignore -$(fd -e h -e hpp -e cpp -e txt -e dox -e cmake)

codespell -I /tmp/.codespellignore -w -$(fd -e h -e hpp -e cpp -e txt -e dox -e cmake)
```
