[dv] Update Xcelium cover ccf

- THis black-boxes pre-verified IPs for Xcelium, which should improve
the coverage numbers.
- This is in-line with our existing VCS cover.cfg file.

The commit relies on the following tool versions:

Xcelium: 21.03.005
VManager: 21.03.003

In addition, it mandates the following env var to be exported to the
execition environment:
XCELIUM_HOME: path/to/xcelium/install/root/dir

The following updates are made to the Xcelium coverage cfg file
(hw/dv/tools/xcelium/cover.ccf):
- Include the common ccf recommended in the Xcelium user guide, which
enables some options.
- Black-box pre-verified modules from coverage collection, but re-enable
the toggles on its ports
- Use env vars in the ccf file instead of hardcoding RTL path
hierarchies.
- Remove commands that are already present in the Xcelium provided ccf
file.
- Improves the covergroup naming
