Add complete integration for the MicroQuickJS JavaScript interpreter,
supporting both CMake and Make build systems with automatic source
acquisition.
Key features:
* FetchContent downloads mquickjs from bellard/mquickjs if local
git repository is not available in interpreters/mquickjs/mquickjs/
* Builds mqjs_stdlib host tool to generate mqjs_stdlib.h and
mquickjs_atom.h headers during build
* Creates libmquickjs library with proper header generation dependencies
to prevent parallel build failures
* Provides mqjs NSH application for interactive JavaScript execution
* Configurable task priority and stack size via Kconfig options
(INTERPRETERS_MQJS_PRIORITY, INTERPRETERS_MQJS_STACKSIZE)
* Supports both 32-bit and 64-bit architectures with appropriate build flags
Files added:
* CMakeLists.txt - CMake build configuration with FetchContent support
* Kconfig - Configuration options for interpreter features
* Make.defs - Make build definitions
* Makefile - Alternative Make-based build support
* .gitignore - Ignores generated files and local mquickjs source directory
