tmpx support improvements for vs64 vscode extension

[laplace7]

• Added schema for file project-config.json. That way code completion
  and documentation is available when users edits the file in vscode.
• Improved tmpx build support:
  • respect project property "main" for main source file
  • added property "cwd" for the current working directory,
    where tmpx is executed. This is necessary so that
    .includes relative to the main.asm file work correctly.
• Added Turbo Macro Pro specific files:
  • grammar
  • language
  • snippets
• Added TMP 06 Compatibility settings:
  • Max Code Line Length
  • Max Comment Line Length
• The languageId for assembly source files is now "tmpx" if
  the toolkit is "tmpx".
• Added a simple tmpx code formatter.
  It only indents code lines that have no leading label.
  Comment lines (starting with a semi-colon) are not changed.
• Removed acme, tmpx, kick from generic asm grammar as there are specific grammars already!
• Removed duplicate command vs64.createProjectTmpx
• Resolve all lables in all source files
• Add problem matcher for llvm toolkit
• Add problem matcher for cc65 toolkit
• Modernize tmpx example (move code in folder src)

Bitte um Review. Vielleicht schaffen wir gemeinsam, den Support für Turbo Macro Pro in VS64 zu bekommen ;-)

I have tested all examples (acme, basic, basic_tsb, cc65, kick, llvm, oscar64, tmpx) under Linux Mint

• opened the project, build and run it
• confirmed that syntax highlighting works
• confirmed that symbol references work
• cc65, llvm, oscar64: symbol references do NOT seem to work in .c-files
• entered a syntax error into the source file, saved the file, and confirmed that problem marker is displayed
• removed the syntax error, build and run it

I have added problem matches for llvm, cc65, tmpx as no problems were shown

Closed PR. I have created a new PR rolandshacks#113 instead!
