Remove mention of rotor from comments (#20297)

* Remove old reference to Rotor in documentation.

All remaining references relate to rotor's role in CoreCLR history.

* Remove rotor comment from enummem.cpp.

I can find no evidence that the presence of g_pStressLog is conditional
on FEATURE_PAL being defined.

* Remove old todo, DbgDllMain looks for thread detach.

* Update nativepipeline.h comment refernce to rotor.

All unix-like systems except android have FEATURE_DBGIPC_TRANSPORT_DI
defined, hence "most unix-like platforms".

* Update some comments to not refer to Rotor.

* Remove some more references to Rotor from comments.

* Remove old comment.

Though maybe this macro should be removed and everywhere use the & operator.
It appears there are only two places that use this macro.
