Bret Sepulveda 566521534d Reland "Add StoragePartitionConfig class."
This reverts commit e16ff9f100.

Reason for revert: Bot was still red after revert: https://ci.chromium.org/p/chromium/builders/ci/WebKit%20Linux%20Leak/15944

Original change's description:
> Revert "Add StoragePartitionConfig class."
> 
> This reverts commit 225f6f4c82.

> Reason for revert: I think this is causing failures in:

> http/tests/workers/worker-usecounter.html
> virtual/omt-worker-fetch/http/tests/workers/worker-usecounter.html

> Original change's description:
> > Add StoragePartitionConfig class.
> > 
> > Introducing StoragePartitionConfig to make it easier for code to
> > directly request the StoragePartition they need instead of having to
> > go through the indirection of site URLs. Grouping the 3 attributes of
> > a config into a class also makes several call sites simpler. This is
> > being done as part of an effort to reduce the amount of code that
> > depends on site URLs.
> > 
> > - Created class for storing the storage partition
> >   <domain, name, in_memory> tuple.
> > - Update GetStoragePartitionConfigForSite() and related code to use
> >   this new class.
> > - Create BrowserContest::GetStoragePartition() method that takes
> >   StoragePartitionConfig as a parameter so future callers do not need
> >   to construct a site URL to get a storage partition.
> > - Remove StoragePartitionImplMap::StoragePartitionConfig struct and
> >   convert StoragePartitionImplMap to use the new StoragePartitionConfig
> >   class.
