Exclude OQD packages, modules and data from wheels (#1403)

**Context:** A number of OQD packages, modules and data files had been
added recently (e.g. #1348 and #1355). However, as support for OQD
devices is still under development, these files should not be included
in the wheels.

**Description of the Change:** Excludes _all_ OQD packages, modules and
data files (such as toml config files) from the wheels. Furthermore, the
OQD device entry in the [Supported devices
documentation](https://docs.pennylane.ai/projects/catalyst/en/stable/dev/devices.html)
has also been removed.
