Global fetchReply option for Client

[Drylozu]

The idea is that fetchReply from MessageComponentInteraction/BaseCommandInteraction #reply (and others) can be global and specified on the Client, as well as allowedMentions and not having to set it for every interaction.reply.

The idea written in code would be something like:

// Main file
const { Client } = require('discord.js');
new Client({
  intents: [...],
  fetchReplies: true
});


// interactionCreate event
interaction.reply({
  content: 'upa'
}); // This will return a Message or APIMessage because fetchReplies is `true` in the client options

This could work now that it's possible to fetch ephemerals too, though I'd still prefer if the API itself could return the data and drop the option completely.
