Proposed functionality

This is similar to issue #18510 but with more clarity.

In issue #17471 the Eaton-C39 proprietary outlet was added. This type of outlet is now found across a variety of manufacturers.

Headers should probably technically be the even-numbered partner of the odd ones listed but I think this is more clear.

Manufacturer	Name	C15 blocked	C15A blocked	C19 blocked	C21 blocked
APC	C13/C15	No	No	Yes	Yes
APC	C13/C15/C19/C21	No	No	No	No
Eaton	C39	No	No	No	No
Panduit	C13/C15	No	No	Yes	Yes
Panduit	C13/C15/C19/C21	No	No	No	No
Schleifenbauer	C13/C15/C19/C21	No	Yes	No	No
Vertiv	C13/C19	Yes	Yes	No	No

Observations:

None of the manufacturers are listing C15A in their overview specs/configurators so we can keep ignoring that I think, even though you can see in their photos that some of them are shaped specifically to let a 16A fit.
The existing in NetBox C15 outlet (C13 "variant") is commonly known to handle C13 as well so no need to add C13/C15 combo.
The existing in NetBox C21 outlet (C19 "variant") is commonly known to handle C19 as well so a combo that supports C21 should be understood to support C19 as well.
Eaton's C39 can clearly accept a C16 (is a C15) so it is unclear why they refer to it as supporting C13/C19.
I don't like putting "Eaton C39" ports on other manufacturer's devices. And I want to discourage the spread of their attempted coopting of the C## naming standard.
There are some other manufacturers (ZPAS, Structure Source, Powertek) trying to call the C13/C19 variant as "IEX" which AFAICT is not a standard.
It seems like the C13 shape of a C13/C19 combo outlet results in C21 fitting even though not intended, but I am not sure 100% on the dimensions.

So overall it is still a bit messy but I think there is a good path forward:

I propose:

Add C13/C19 combo port type to represent the multiple manufacturers shipping this
- Vertiv
- Other "IEX" ones
Add C15/C21 combo port type to represent the multiple manufacturers shipping this
- APC
- Panduit
- Schleifenbauer

Use case

More accurately model PDU outlets.
