_SystemProperties build()

Finalizes and creates a new immutable `_SystemProperties` snapshot.

Example:

    final props = _SystemProperties.builder()
      .compilationMode(CompilationMode.release)
      .build();

    print(props.isProductionMode()); // true

## Implementation

    _SystemProperties build() {
      return _SystemProperties(
        compilationMode: _compilationMode,
        runningFromDill: _runningFromDill,
        runningAot: _runningAot,
        runningJit: _runningJit,
        entrypoint: _entrypoint,
        launchCommand: _launchCommand,
        ideRunning: _ideRunning,
        dependencyCount: _dependencyCount,
        configurationCount: _configurationCount,
        watchModeEnabled: _watchModeEnabled,
      );
    }
