Nestor Soriano 70a1cb2f1f Revert improved filtering for variations.
This commit reverts the functionality introduced in PR #26260
(later refined by #27175, #27190, #27508) in which filtering by
attribute using the layered nav widget was improved to handle the
cases of variations out of stock. The revert is a response to the
numerous problems reported by users in Woo 4.4 and 4.5

Not all the code has been reverted, only the code that resulted in
visible functionality changes. Thus, the code that generates
term relationships for variations is still in place to keep database
consistency and to keep the reverting changes to the minimum needed.

Nestor Soriano 71fccd6a07 Fix: pagination controls not displaying in products list.
This bug was introduced in #26260. The sequence is:

1. WC_Query::adjust_posts_count runs, to handle found_posts filter,
   this indirectly executes wc_setup_loop.
2. At this point $GLOBALS['wp_query']->max_num_pages hasn't been set
   yet, and has a value of 0. Thus the loop variable total_pages
   is set to 0.
3. Later wc_setup_loop runs again and this time
   $GLOBALS['wp_query']->max_num_pages is already set, but since
   the loop variable total_pages already exists, it keeps its
   value of 0.
4. The pagination controls never show if total_pages is less than 2.

The fix consists of hooking into the_posts to set the value of
total_pages again, at that point $GLOBALS['wp_query']->max_num_pages
is already set.

Nestor Soriano 86c88f1750 Fix: incorrect adjustment of post count in WC_Query.
PR #26260 introduced a handler for 'found_posts' filter in WC_Query
class in order to adjust the count depending on the visibility
of variation products. However the handler incorrectly assumed
that the filter was triggered only when listing products, when
actually it's also triggered for any post type e.g. pages.
In these cases the post count was set to zero, which caused bugs.

Now the handler starts with the originally supplied posts count,
and only decrements it when a post is a product AND is not visible.

Nestor Soriano 9142e27a19 Adjustments in WC_Query::adjust_posts_count
Two adjustments were needed:

- Adjust the count even when there's no nav filtering in the query.
  This is necessary to present the proper products count.
  even when the woocommerce_product_is_visible filter is used.
- Account for the case where $GLOBALS['wp_query']->posts
  returns objects instead of ids (for example when viewing
  a product page).

Nestor Soriano 50e8f27bc7 Fix visibility of variable products with layered nav filtering.
The layered nav filtering doesn't work well with variable products
when some variations have stock and other don't. When a term is
selected in the widget, a variable product having no stock for
the variation corresponding to that term but having stock for
other variations will be displayed, but it shouldn't.

This commit fixes that by introducing two changes:

- A new override of "is_visible" for WC_Product_Variable that
  looks at the supplied filters, compares them against the corresponding
  available variations and calculates the visibility based on
  the query type (OR or AND).

- A hook on the "found_posts" filter in WC_Query, that adjusts
  the posts count based on the found products visibility
  when there are filters available; this is needed to sync the
  "displaying X posts" messages and the paging when variable
  products are hidden due to stock status.

Additionally, the visibility calculated in "found_posts" is cached
as loop variables so that it isn't calculated again when actually
displaying the products.
