Official language and syntax support for DTX 1.0.0.

Current extension name: DTX by DTX Office.

DTX 2 development is open in the compiler repository, but active public syntax remains DTX 1.0.0. This extension must not highlight future DTX 2 keywords until those features are implemented and released officially.

DTX Language Support does not include the DTXC compiler.

Installing this extension provides editor support only and does not make DTX programs executable.
