implement table type access modifiers

[jackdotink]

Implements table type access modifiers:

type foo = {
    read bar: number
    write baz: string,
}

[Kampfkarren]

Add #[cfg_attr(feature = "serde", serde(skip_serializing_if = "Option::is_none"))]

[Kampfkarren]

You didn't do this

[jackdotink]

I added serde_option or whatever it is to the entire enum. If you'd rather have this, I can do that instead.

[Kampfkarren]

Do you mean display_option? That's for display: the thing I gave is to not include it in serde if it's unset.

[Kampfkarren]

Need tests for this as well

This should require the syntax property access modifiers RFC to be implemented into the luau-lang/luau repository.
I don't think it's implemented yet, and I tried the example provided in the PR description and ran it with Luau, but it gave me a syntax error.

@DataM0del try again because it works for me

I'll update my Luau version. I wish though that Luau would have a --version command but the PR for that isn't moving because of complaints about how you have to change the version macro value to the current version or etc.

[DataM0del]

I updated. It works now.

Actually, it doesn't work because of the trailing comma.

This also needs the serde thing
