fix: accept VISIBLE/INVISIBLE index and column attributes in CREATE TABLE and CREATE INDEX

MySQL 8.0 invisible indexes (KEY idx (col) INVISIBLE) and invisible columns
failed to parse inside CREATE TABLE, and CREATE INDEX ... INVISIBLE failed
too, because CreateParameter() did not accept the K_VISIBLE/K_INVISIBLE
tokens. The ALTER TABLE productions already support them (#2076 was fixed
for ALTER TABLE only, via #2234); this covers the CREATE statements, which
share CreateParameter(). Tests cover index and column visibility, mixing
visibility with other index options in either order, and quoted columns
named visible/invisible.
