[mysql/oracle] Add remaining ports to support all targets.

[kaby76]

This PR implements the rest of the ports of the mysql/oracle grammar. This is a necessary first step in generating each of the ports automatically from the official source (here). It also refactors the code to be more in line with standard OO development practices. These ports are necessary mainly because people want to pick a grammar and run with it. Asking them to write a port of the grammar is time-consuming and difficult.

Previously, from the original Antlr4ng port, initialization was done in the driver:

grammars-v4/sql/mysql/Oracle/original/TypeScript/demo.ts

Lines 23 to 27 in 00a96c9

	lexer.serverVersion = 80200;
	lexer.sqlModeFromString("ANSI_QUOTES");
	lexer.charSets = charSets;
	parser.serverVersion = lexer.serverVersion;
	parser.sqlModes = lexer.sqlModes;

This is actually a bad place to put initialization because it requires the user to read the driver code or readme. No one does either, and they just want it to "work." Also, driver code are not part of the grammar. Initialization should be done in a constructor, in line with OO practices.

In addition, the class SqlMode should be in its own file, not embedded in the lexer base class.

grammars-v4/sql/mysql/Oracle/original/TypeScript/MySQLBaseLexer.ts

Lines 12 to 19 in 00a96c9

	export enum SqlMode {
	NoMode,
	AnsiQuotes,
	HighNotPrecedence,
	PipesAsConcat,
	IgnoreSpace,
	NoBackslashEscapes,
	}

It is used in the parser.

grammars-v4/sql/mysql/Oracle/original/TypeScript/MySQLBaseRecognizer.ts

Line 7 in 00a96c9

import { SqlMode } from "./MySQLBaseLexer.js";

The method that creates a Set<SqlMode> is in the lexer. It should be in the class SqlModes.

What was done?

• The existing ports (Antlr4ng CSharp Java Python3 TypeScript) were fixed to set defaults in constructors.
• The custom Test.* files were removed.
• StackQueue<> was removed and all ports now use a standard queue data structure.
• The Cpp, Dart, Go, and JavaScript ports were added.
