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
