Add a filter to disable Homepage cache clearing

[alfonso100]

Is your feature request related to a problem? Please describe.
Quite often, we get support tickets where the customers want to disable all forms of cache clearing.
We do have a public doc and helper plugin for this:
https://docs.wp-rocket.me/article/137-disable-automatic-cache-clearing

However, the homepage cache cleanups can't be stopped.

The code of the helper plugin has been gaining complexity through the years, as from time to time we discover new ways where the cache is cleared: https://github.com/wp-media/wp-rocket-helpers/blob/master/cache/wp-rocket-no-cache-auto-purge/wp-rocket-no-cache-auto-purge.php

Describe the solution you'd like
Add a filter to prevent the homepage cache from clearing.

A customer, Emiel (from the HS ticket below) suggested the following edit to our purge.php code:

	// Never forget to purge homepage and their pagination.
	if(apply_filters( 'rocket_clean_home_after_clean_post', true, $post_id ) === true ) {
		rocket_clean_home( $lang );
	}

Describe alternatives you've considered
@joejoe04 suggested adding a more global filter to completely turn off all forms of cache cleanups in a consistent way. Including everything.
