feat(@angular-devkit/build-angular): add JSON build logs when using the application builder

[alan-agius4]

This change implements the capability to display JSON build logs in the terminal instead of a format readable by humans. This is particularly useful for hosting providers, as it allows them to effortlessly access the necessary information without having to parse the JSON configuration.

To enable this output, set the NG_BUILD_LOGS_JSON=1 environment variable. Additionally, warnings, errors, and logs are automatically colorized when the standard output is a WritableStream. You can disable the colors by using the FORCE_COLOR=0 environment variable.

FORCE_COLOR=0 NG_BUILD_LOGS_JSON=1 ng b
{
  "errors": [],
  "warnings": [],
  "outputPaths": {
    "base": "file:///usr/local/test/home//test-project/dist/test-project",
    "browser": "file:///usr/local/test/home//test-project/dist/test-project/browser",
    "server": "file:///usr/local/test/home//test-project/dist/test-project/server"
  },
  "serverEntryFile": "file:///usr/local/test/home//test-project/dist/test-project/server/server.mjs",
  "prerenderedRoutes": [
    "/"
  ]
}

NG_BUILD_LOGS_JSON=1 ng b
{
  "errors": [],
  "warnings": [],
  "outputPaths": {
    "base": "file:///usr/local/test/home//test-project/dist/test-project",
    "browser": "file:///usr/local/test/home//test-project/dist/test-project/browser",
    "server": "file:///usr/local/test/home//test-project/dist/test-project/server"
  },
  "serverEntryFile": "file:///usr/local/test/home//test-project/dist/test-project/server/server.mjs",
  "prerenderedRoutes": [
    "/"
  ]
}
