[CALCITE-4847] Parse SQL with BigQuery-style quoted identifiers and character literals

In BigQuery, identifiers are quoted with backticks and an
included backtick is escaped with a backslash; character
literals are quoted with single-quotes or double-quotes and
an included quote is escaped with a backslash.

The parser enters this mode if you specify 'dialect=BIG_QUERY',
'lex=BIG_QUERY', or 'quoting=BACK_TICK_BACKSLASH' in the
connect string.

The connect string parameter 'quoting' previously allowed
values 'DOUBLE_QUOTE', 'BACK_TICK' and 'BRACKET', and now
also allows 'BACK_TICK_BACKSLASH'.
