IMPALA-14912: Calcite Planner: Fix date string parsing
This commit fixes parsing for the following date strings SQL
select DATE '1999-01-01';
select DATE "1999-01-01";
This essentially reverts an earlier fix, IMPALA-13525, which was
way more complicated than it needed to be. The Impala StringLiteral
already handles escaped strings, so there is no need to remove the
escapes within the Calcite parser. The changes in Parser.jj reflect
the major part of the reversion, as well as removing the ParserUtil.java
file.
A change also had to be made in the ImpalaRexExecutor where the constant
folding was done. This completes the UTF-8 constant folding commit for
the Calcite Planner (IMPALA-10349)
One more change was made with the unhex function. Unhex can return a
non-UTF8 string. Impala can handle this in a StringLiteral, but Calcite
cannot. Because of this, the constant folding for unhex when the string
is non-UTF8 is done at physical node creation time rather than during
the optimization phase.
