Add Raptor Lake integrated MAC support

[kamber-intel]

Some Raptor Lake SKUs include integrated TSN MACs.

The EHL plugin can be used as a reference: https://github.com/Avnu/detd/blob/30aeb789903ae66424d0f1c3ce87406d863a0467/detd/devices/intel_mgbeehl.py

Some suggested changes:

• Rename as intel_mgberpl.py
• Rename class and references as IntelMgbeRpl, Raptor Lake, etc
• Use the device ID as in the Linux driver, e.g. in the dwmac-intel.c file: https://github.com/torvalds/linux/blob/f016f7547aeedefed9450499d002ba983b8fce15/drivers/net/ethernet/stmicro/stmmac/dwmac-intel.c#L1201
• Change the number of Tx and Rx queues to 4 each

That should be enough for a first round of testing.

We are leaving out aspects like launch time control or ingress optimization until the listener stream support and launch time control support are merged.

What exactly is missing for Raptor Lake support? I am using detd on a i7-1360P without any CPU related issues.

@koalo good point, the title was not completely clear. It refers to the integrated TSN MAC in Raptor Lake, as handled by detd e.g. the Elkhart Lake or Tiger Lake plugins. Let me add some description details to make that clear.
