EF.Functions support for Cosmos

[danejur]

When playing around with EFCore's Cosmos provider last night, I made the unfortunate discovery that Cosmos doesn't currently have support (or an implementation, rather) for EF.Functions, the helper class that provides some additional SQL operators and functions (notably, for my use cases, Contains and Like). Is there any plan to add a Cosmos-specific implementation of these extensions?

Likely duplicate of #16143

@ajcvickers Saw that thread, and thought the same. The only thing I'd point out is that like isn't included on the list of supported built in functions, which I imagine is because like isn't technically a function nor does it seem to be currently supported by Cosmos in general. Feel free to close this issue if you feel that it's a dupe, though!
