feat: add .send() methods to message parameter structs

[skywardboundd]

Closes #3055

[novusnota]

And the changes to core-send.mdx have to be reversed + 3 new send functions added there. One moment.

UPD: Done, but I'm still not in favor of changing every usage example in the docs.

• Replacing send(SendParameters { ... }) with SendParameters { ... }.send()
• Updating multiple Tact language documentation files to reflect this new API call style.

Hold on, let's revert changes to the documentation in all places but the core-send.

I've previously vaguely expressed my concerns here, but now I am certain — we must not replace older examples with the new code that won't work for users until 1.7 is released, because docs here will be published immediately on merge, unlike Tact 1.7. Furthermore, not all users are on the latest version, and we still have many folks that use versions prior to 1.6.0.

Sehr gut.

To be actually semantically closer to what's going on with messages under the hood, we might want to rename the .send() to the .queue().

And in the end, perhaps we're looking at having a single msg {} statement instead of all those functions. That statement will compose the message declaratively, and then we'll be able to call .queue() on the resulting message cell, specifying the mode of sending.
