fix: filtering promise properties in object literal completion - #59316

Tests for completions can be written like this:
https://github.com/microsoft/TypeScript/blob/f37482cd16118409284e015409deaf14b416b4a0/tests/cases/fourslash/completionsPropertiesPriorities.ts

Looks like you're introducing a change to the public API surface area. If this includes breaking changes, please document them on our wiki's API Breaking Changes page.

Also, please make sure Daniel Rosenwasser (@DanielRosenwasser) and Ryan Cavanaugh (@RyanCavanaugh) are aware of the changes, just as a heads up.

This looks good to me, though #59316 was accepted without determining whether or not the items should be prioritized or filtered, and this PR filters them out entirely.

I assume that ordering them is going to be a challenge, so are we okay with not providing promise-like method completions here?

Starting jobs; this comment will be updated as builds start and complete.

Hey Andrew Branch (@andrewbranch), I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/163182/artifacts?artifactName=tgz&fileId=FB6676671E04A4C6C1239CBAE0D3D2733BB015E08A215E8561269BB16027CF7302&fileName=/typescript-5.6.0-insiders.20240808.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/pr-build@5.6.0-pr-59316-5".;
