[dell] S5248F-ON support broadcom common config

As per sonic-net#20802 broadcom provides a common configuration for silicon-
wide application configuration settings.  More details can be
found here: https://github.com/sonic-net/SONiC/blob/master/doc/platform/common_config.md

Broadcom also updated the common configuration files in sonic-net#20802
which contains a lot of settings that are otherwise not included
in the Dell S5248F platform config.

This commit creates the "dummy" `common_config_support` as required to
load the common configuration, as well as removes any duplicate
entries.

This also adds the missing `pcie.yaml` file generated via
`pcieutil generate` which corrects these messages:
```
2024 Dec  1 20:16:42.639522 sw2 NOTICE root: /usr/bin/pcie-check.sh : pcie.yaml does not exist! Can't check PCIe status!
```
