Support SubresourceFilter on Dedicated Worker for off-main-thread-fetch
This CL introduces WebDocumentSubresourceFilter::Builder class.
SubresourceFilterAgent::WillCreateWorkerFetchContext() creates the builder
object and set to the WebWorkerFetchContext on the main thread.
WebWorkerFetchContext::TakeSubresourceFilter() is called by the constructor of
WorkerFetchContext on the worker thread to creates a WebDocumentSubresourceFilter
using the builder object.
Note: This CL adds SubresourceFilter supports only for Dedicated Workers with
off-main-thread-fetch optimization. Currently SubresourceFilter is not supported
in Shared Workers and Service Workers regardless of the off-main-thread-fetch
optimization. See crbug.com/739597#c2
