MDEV-24576 Atomic CREATE TABLE

There are a few different cases to consider

Logging of CREATE TABLE and CREATE TABLE ... LIKE
- If REPLACE is used and there was an existing table, DDL log the drop of
  the table.
- If discovery of table is to be done
    - DDL LOG create table
  else
    - DDL log create table (with engine type)
    - create the table
- If table was created
  - Log entry to binary log with xid
  - Mark DDL log completed

Crash recovery:
- If query was in binary log do nothing and exit
- If discoverted table
   - Delete the .frm file
-else
   - Drop created table and frm file
- If table was dropped, write a DROP TABLE statement in binary log

CREATE TABLE ... SELECT required a little more work as when one is using
statement logging the query is written to the binary log before commit is
done.
This was fixed by adding a DROP TABLE to the binary log during crash
recovery if the ddl log entry was not closed. In this case the binary log
will contain:
CREATE TABLE xxx ... SELECT ....
DROP TABLE xxx;

Other things:
- Added debug_crash_here() functionality to Aria to be able to test
  crash in create table between the creation of the .MAI and the .MAD files.
