AppCache: Add command-line flags for default quota and disk size.

This CL introduces the following command-line switches:
- max-appcache-disk-cache-size-mb - limits the size of the HTTP disk
  cache used by AppCache for all origins
- max-appcache-origin-cache-size-mb - limits the per-origin AppCache
  quota when no QuotaManager is present

The CL is heavily based on the following reverted commits:
1. https://crrev.com/c/974804 - Set the maximum cache size per an origin
    in the command line for application cache
2. https://crrev.com/c/979877 - Pass the maximium disk cache size of
    appcache in the command line to appcache thread
