Auto merge of #20212 - mkollaro:webidlcmake, r=jdm

Regenerate all WebIDLs when one of them changes

WebIDL files have dependencies between each other, but cmake doesn't have any
information about them. This can cause it to not update all the changed bindings
when switching branches.

<!-- Either: -->
- [ ] There are tests for these changes OR
- [x] These changes do not require tests because it's a minor change in the build dependencies.
Switching between two of my branches was previously failing because a change in WebGL1 bindings didn't re-generate the WebGL2 bindings. I verified that it works with this patch.
