Possible WebAssembly JSObject Improvements

[miroljub1995]

I see that some methods on JSObject are called with helper methods defined here:

runtime/src/mono/browser/runtime/invoke-js.ts

Line 425 in 3aa1ec5

export function get_property (self: any, name: string): any {

runtime/src/mono/browser/runtime/invoke-js.ts

Line 420 in 3aa1ec5

export function set_property (self: any, name: string, value: any): void {

runtime/src/mono/browser/runtime/invoke-js.ts

Line 430 in 3aa1ec5

export function has_property (self: any, name: string): boolean {

Why we do not import the native ones and deprecate the old ones:
