Subject: content: allow embedder to prevent locking scheme registry
The //content layer requires all schemes to be registered during startup,
because Add*Scheme aren't threadsafe. However, Electron exposes the option to
register additional schemes via JavaScript in the main process before the app
is ready, but after the //content layer has already locked the registry.
This allows embedders to optionally keep the scheme registry unlocked, and it
is their responsibility to ensure that it is not accessed in a way that would
cause potential thread-safety issues.
Previously upstreamed patch: https://chromium-review.googlesource.com/c/chromium/src/+/1637040
This change was lost during upstream refactor in
https://chromium-review.googlesource.com/c/chromium/src/+/1901591, we should try
re-submitting the patch.
