Validates glob patterns eagerly in RouteHandler and WebSocketRouteHandler
constructors so an invalid pattern like '{foo' throws immediately when
page.route() / context.route() is called, rather than silently aborting
requests at match time via a SyntaxError from new RegExp().
Fixes: microsoft#40422

There was a problem hiding this comment.
let's move this to the dispatcher / server side, so it also applies to our language ports.
Move glob pattern validation from the client-side WebSocketRouteHandler constructor to setWebSocketInterceptionPatterns in both BrowserContext and Page dispatchers, so the error also surfaces for language ports.

_updateInterceptionPatterns is called next line at both constructions sites and it does the glob validation on the server, do we still need to duplicate the logic here?
