[native] migrate threadActivityStore to SQLite

Summary:
This migrates threadActivityStore to SQLite

Depends on D11615

Test Plan:
Rebased to prior commit without threadActivity sqlite changes. Populated redux persist with thread activity entries via dispatch actions. Rebased back to current commits without migration. Encountered state difference due to missing migration. Ran the migration and previous entries are included in the sqlite database
