Support static and instance members having the same name in IDLs (#36523)

Browse source 
This is needed to implement features like `Response.json` which is a
static helper added to the fetch spec which overlaps with the `json`
instance method `Response` has from `Body`.

Partly based these changes on what Firefox does for this same issue.
(https://searchfox.org/mozilla-central/source/dom/bindings/Codegen.py
and
https://searchfox.org/mozilla-central/source/dom/bindings/Configuration.py
specifically keying `binaryNameFor` on name and `isStatic`).

Testing: I locally updated the Response.webidl to contain the new static
`json` and it compiles.
