Specification

Summary
Fixes a bug in the predictable-storage-quota that allows Incognito mode to be 
detected. A change introduced recently to Stable, buckets the result of the 
StorageManager's estimate API for sites that do not have unlimited storage 
permission to max(10Gib, ceil(actual_quota_in_Gib)) + usage. However, in 
incognito mode, the actual quota value is based on a fraction of available RAM, 
instead of the disk space - providing an Incognito detection surface. This 
change fixes the value of this API for Incognito Mode to the maximal bucket of: 
usage + 10Gib. Discussion on the original feature available here:

 This is a new Chromestatus in place of an original PSA, as this launch should 
start with an I2E to ensure the breakage risk is properly addressed. See
