Merge WebUSB notification flag into experimental web platform features.
The WebUSB notification flag tells Chrome to scan for WebUSB-enabled
devices when they are connected to the system. This patch will expose
this code to a larger population to make sure that such scanning does
not introduce new crashes and reduce the number of flags developers must
enable to try out WebUSB.
