Do not show delete message option in message action sheet if delete time is passed or message delete is not allowed on that realm.

Similiar to #2792.

@zulipbot claim

We might want to keep the option but show an error.
Hidden options are usually very opaque to users, they might even report the missing item as a bug.

ya May be disabled option, with little bit of info , why it is disabled?

[timabbott]

I would start with hiding the option; it's less work (and what we do on the webapp, which nobody has complained about).

I believe there are two realm-specific server settings we'll need to read, in order to fix this issue. (I'm less sure about these than I am for #2792, but I believe these points follow fairly clearly from the issue description.)

• Whether the realm allows deleting messages
• The time limit on deleting messages

So in particular we can't do something like assume message-deleting is allowed and use a hard-coded time limit of 60 minutes, just because those are the settings on CZO. 🙂

It occurs to me that we also have to have some pretty subtle logic with some more inputs, like the user's role. Let's get #3898 done before this if we can.
