INVALIDATE METADATA <table> should set a better createEventId

"INVALIDATE METADATA <table>" can be used to bring up a table in Impala's catalog cache if the table exists in HMS. For instance, when HMS event processing is disabled, we can use it in Impala to bring up tables that are created outside Impala.

The createEventId for such tables are always set as -1:
https://github.com/apache/impala/blob/6ddd69c605d4c594e33fdd39a2ca888538b4b8d7/fe/src/main/java/org/apache/impala/catalog/CatalogServiceCatalog.java#L2243-L2246

This is problematic when event-processing is enabled. DropTable events and RenameTable events use the createEventId to decide whether to remove the table in catalog cache. -1 will lead to always removing the table. Though it might be added back shortly in follow-up CreateTable events, in the period between them the table is missing in Impala, causing test failures like IMPALA-12266.

A simpler reproducing of the issue is creating a table in Hive and launching Impala with a long event polling interval to mimic the delay on events. Note that we start Impala cluster after creating the table so Impala don't need to process the CREATE_TABLE event.

hive> create table debug_tbl (i int);

bin/start-impala-cluster.py --catalogd_args=--hms_event_polling_interval_s=60

Drop the table in Impala and recreate it in Hive, so it doesn't exist in the catalog cache but exist in HMS. Run "INVALIDATE METADATA <table>" in Impala to bring it up before the DROP_TABLE event come.

impala> drop table debug_tbl;
hive> create table debug_tbl (i int, j int);
impala> invalidate metadata debug_tbl;

The table will be dropped by the DROP_TABLE event and then added back by the CREATE_TABLE event. Shown in catalogd logs:
