OpenSearch SQL dialect.

OpenSearch SQL is syntactically close to MySQL but accepts both backticks and
double-quotes as identifier delimiters. Treating ``"`` as an identifier (rather
than a string delimiter, as MySQL does) is what keeps mixed-case column names
from being emitted as string literals after a SQLGlot round-trip.
