Marking as `DRAFT` to get feedback from reviewers in case they notice any obvious issues while I continue testing. --- Depends on D10818

NOTE: Marking as `DRAFT` to get feedback from reviewers in case they notice any obvious issues while I continue testing. This migration basically converts `ClientDBThreadInfo`s in the SQLite `threads` store to `RawThreadInfo`s and then back to `ClientDBThreadInfo`s. The function that takes us from `ClientDBThreadInfo` -> `RawThreadInfo` handles converting both legacy and minimallyEncoded `ClientDBThreadInfo` to minimally encoded `RawThreadInfo`s (we decided against splitting `ClientDBThreadInfo` into separate types since the relevant fields were all string encoded JSON blobs. `convertClientDBThreadInfoToRawThreadInfo` was tested thoroughly as part of the original `native` migration and has "excessive" validation to ensure that we're dealing with correctly formed `ClientDBThreadInfo`s: {F1089007} --- Depends on D10818
