Feature or enhancement

Proposal:

Currently, attempting to await something that cannot be awaited results in this error message:

import asyncio

async def main():
    await 1

asyncio.run(main())

# TypeError: object int can't be used in 'await' expression

I recently encountered this for the first time when the unawaitable object was a method (which was not being called), and found the phrase "object method" unclear. This PR changes the error message so that the name of the class precedes the word "object" and appears in single quotes. A similar construction appears elsewhere in the code base.

>>> 1[2]
TypeError: 'int' object is not subscriptable

The PR already exists at #114090 but will be amended momentarily to implement changes suggested by Jelle and to resolve failed tests.

Has this already been discussed elsewhere?
