chore: add correct defaults

[marco-ippolito]

cc @nodejs/typescript
I also wonder which other options we should set by default during transformation

interface TransformConfig {
    /**
     * @see https://www.typescriptlang.org/tsconfig#verbatimModuleSyntax
     */
    verbatimModuleSyntax?: boolean;
    /**
     * Native class properties support
     */
    nativeClassProperties?: boolean;
    importNotUsedAsValues?: "remove" | "preserve";
    /**
     * Don't create `export {}`.
     * By default, strip creates `export {}` for modules to preserve module
     * context.
     * 
     * @see https://github.com/swc-project/swc/issues/1698
     */
    noEmptyExport?: boolean;
    importExportAssignConfig?: "Classic" | "Preserve" | "NodeNext" | "EsNext";
    /**
     * Disables an optimization that inlines TS enum member values
     * within the same module that assumes the enum member values
     * are never modified.
     * 
     * Defaults to false.
     */
    tsEnumIsMutable?: boolean;
}

I think importNotUsedAsValues: "preserve" others idk which are defaults

LGTM.

I think the only behavioral change this PR will achieve on Node is to fix nodejs/node#54514 via the addition of noEmptyExport: true

The rest is just codifying existing usage. Similarly you could add:

Suggested change

	},
	useDefineForClassFields: true,
	},

In TypeScript, VMS replaces that need to set INUAV. But I don't know if that's the case in SWC so keeping it fully explicit (as you have now) until we hear otherwise from SWC folk seems good.

apparently useDefineForClassFields does not exist in configuration
