Support Tarantool Lua debug

[georgiy-belyanin]

There is a Tarantool Lua Debugger extension allowing one to debug a Tarantool application from the Visual Studio Code. It'd nice to provide similar functionality within this extension.

There is an official Tarantool debugger called tarantool-lua-debugger-vscode for Tarantool 2.x and earlier versions. It is available in the marketplace too.

EmmyLuaDebugger also seems to work rather good with Tarantool. It offers the following features.

• Breakpoints.
• Step-by-step execution within the fiber.
• Multiple files support.
• Interacting with the local variables, console at the debug mode.

It's been tested by me in VS Code.

Though it needs a few fixes & hacks within the original implementation to work with Tarantool. I hope I have a chance to provide them later.

It turned out the only problem I came across when tested EmmyLuaDebugger with Tarantool was caused by spurious wake ups. Probably they are specific to ARM64 or whatever. A PR with a fix has been created in the upstream repo: EmmyLua/EmmyLuaDebugger#75.
