MySQL parser does not support inline comments

[vaitkus]

Issue noticed in version 1.66 (1ef083e).

MySQL parser fails when the input schema contains inline comments in the table create statement. For example, trying to parse the statement below:

CREATE TABLE `check` (
    test_time time /* mariadb-5.3 */ DEFAULT NULL
);

results in the following error:

       ERROR (line 1): Invalid statement: Was expecting comment, or use, or
                       set, or drop, or create, or alter, or insert, or
                       delimiter, or empty statement

The statement parses correctly when the /* mariadb-5.3 */ part is removed.

MySQL v8.0.40 manages to parse both versions of the statement.

Such comments are automatically generated when dumping the schema with newer versions of MariaDB.
