{M103 PICK} [Track postMessage usage] (3) Add 3P info retention to BlinkStorageKey and mojom

This CL spreads the 3P info retention from the prior CL through the rest
of the StorageKey stack. This preserves the information that would be
set if third party storage partitioning was enabled for measurement
purposes. Our prior change did not propagate the information deep
enough and we weren't able to detect 3P usage of post message.
**This will be picked into M103**

This CL is a part of a series:
(1) Consolidate existing metrics
(2) Track cross-origin calls
(3) Add 3P support to BlinkStorageKey and mojom

(cherry picked from commit aefcdae3aa43d4845a02d5188d1fa2daf224d675)
