Introduces a mechanism to dynamically load a custom esbuild plugin when the application builder is executed within a Bazel environment. This is enabled by a new `bazelEsbuildPluginPath` option, which is derived from the `NG_INTERNAL_ESBUILD_PLUGINS_DO_NOT_USE` environment variable. The path is only resolved if the `BAZEL_BINDIR` and `JS_BINARY__EXECROOT` environment variables are also present, ensuring the logic is only active during a Bazel build. The builder dynamically imports the plugin from the specified path and adds it to the esbuild pipeline, allowing for build-system-specific customizations. (cherry picked from commit ec739d7)
