Eliminate use of `extract()` in `WP_List_Table::ajax_response()`:

* Extracting `$this->_args` is unnecessary since none of the variables produced are present in the method.
* `total_items` and `total_pages` can be read directly from `$this->_pagination_args`

See #22400.

Eliminate use of `extract()` in `WP_Plugin_Install_List_Table::get_table_classes()`. It only needs to read `plural`, no need to extract.

Eliminate use of `extract()` in `WP_List_Table::pagination()`:

* Set variables instead of extracting `$this->_pagination_args`
* Weird: `$infinite_scroll` is only presently set in subclasses of `WP_List_Table` and never initialized otherwise.

Eliminate use of `extract()` in `WP_Terms_List_Table::display_rows_or_placeholder()`:

* Set variables for `$page` and `$number`
* `list(...) = $this->get_column_info()` can be removed, as none of the variables returned are used.
* `orderby` and `search` can be checked from `$args`, leaving no reason to extract

Eliminate use of `extract()` in `post_tags_meta_box()` and `post_categories_meta_box()`.

Both functions only need to read `taxonomy`, yet they extract every available variable from `$box['args']`. Even if those variables were useful, there is no attempt to pass them to anything, and scope in PHP does not allow them to be scooped up by inner functions without being passed directly.
