IMPALA-12934: Added Calcite parsing files to Impala
Adding the framework to create our own parsing syntax for Impala using the base Calcite Parser.jj file. The Parser.jj file here was grabbed from Calcite 1.36. So with this commit, we are using the same parsing analysis as Calcite 1.36. Any changes made on top of the Parser.jj file or the config.fmpp file in the future are Impala specific changes, so a diff can be done from this commit to see all the Impala parsing changes. The config.fmpp file was grabbed from Calcite 1.36 default_config.fmpp. The Calcite intention of the config.fmpp file is to allow markup of variables in the Parser.jj file. So it is always preferable to modify the default_config.fmpp file when possible. Our version is grabbed from https://github.com/apache/calcite/blob/main/core/src/main/codegen/config.fmpp and slightly modified with the class name to make it compile for Impala. There's no unit test needed since there is no functional change. The Calcite planner will eventually make changes in the ".jj" file to support the differences between the Impala parser and the Calcite parser.
