[build] Disable implicit fallthrough warnings for sqlite3 (#12855)
The sqlite3 source code has a lot of implicit fallthroughs in case statements. They are documented with comments but even though gcc provides options to use these comments to suppress the warnings, that's not always reliable. For instance, it may fail if an #ifdef follows the comment or if the comment is within a block scope used for a case. With gcc version '(Ubuntu 7.3.0-16ubuntu3) 7.3.0' I get warnings similar to the below: ../../../vendor/sqlite/src/sqlite3.c: In function ‘sqlite3_db_status’: ../../../vendor/sqlite/src/sqlite3.c:20251:10: error: this statement may fall through [-Werror=implicit-fallthrough=] op = SQLITE_DBSTATUS_CACHE_WRITE+1; So disable the implicit falltrhough warnings for that library. Note that -Wno-error=implicit-fallthrough is not used to keep the build silent since this is vendor library.
