feat: add support for WebHID (#30213)
* feat: add support for WebHID

* Apply suggestions from code review

Co-authored-by: Jeremy Rose <jeremya@chromium.org>

* Address review feedback

* Address review feedback

* chore: clear granted_devices on navigation

Also added test to verify devices get cleared

* fixup testing for device clear

* make sure navigator.hid.getDevices is run on correct frame

* clear granted devices on RenderFrameHost deletion/change

* manage device permissions per RenderFrameHost

This change makes sure we don't clear device permission prematurely due to child frame navigation

* Update shell/browser/api/electron_api_web_contents.cc

Co-authored-by: Jeremy Rose <jeremya@chromium.org>

* apply review feedback from @zcbenz

* Match upstream ObjectMap

This change matches what ObjectPermissionContextBase uses to cache object permissions: https://source.chromium.org/chromium/chromium/src/+/main:components/permissions/object_permission_context_base.h;l=52;drc=8f95b5eab2797a3e26bba299f3b0df85bfc98bf5;bpv=1;bpt=0

The main reason for this was to resolve this crash on Win x64:
ok 2 WebContentsView doesn't crash when GCed during allocation
Received fatal exception EXCEPTION_ACCESS_VIOLATION

Official Guides

Please make sure that you use the documents that match your Electron version. The version number should be a part of the page URL. If it's not, you are probably using the documentation of a development branch which may contain API changes that are not compatible with your Electron version. To view older versions of the documentation, you can browse by tag on GitHub by opening the "Switch branches/tags" dropdown and selecting the tag that matches your version.
