feat: implement drop multiple tables

[sarailQAQ]

I hereby agree to the terms of the GreptimeDB CLA.

Refer to a related PR or issue link (optional)

close #4020

What's changed and what's your intention?

Implemet dropping multiple tables in the single statement.

If any tables do not exist without IF EXISTS, the statement fails with an error and don`t make any change, referencing MySQL.

It works for SQL requests, not ready for gRPC.

Checklist

• I have written the necessary rustdoc comments.
• I have added the necessary unit tests and integration tests.
• This PR requires documentation updates.

	DROP TABLE IF EXISTS foo;
	create table foo (
	host string,
	ts timestamp DEFAULT '2023-04-29 00:00:00+00:00',
	cpu double default 0,
	TIME INDEX (ts),
	PRIMARY KEY(host)
	) engine=mito;
