Update user agent info capabilities (#45632)

* Add user_agent optional param to static methods

* Pass useragent to static methods

Pass down the user agent in the methods get_browser, get_platform and
get_desktop_platform. Another step in the direction of being able to use
this class to parse user agent strings and not just the value set on
$_SERVER['HTTP_USER_AGENT']

* Use useragent in is_tablet method

* Add detection for 6 popular browsers

We can now detect 6 additional popular browsers that were previously
classified as "other":
 - Samsung Internet (default on Samsung devices)
 - UC Browser (popular in Asia)
 - Yandex Browser (popular in Russia)
 - Vivaldi (power users)
 - MIUI Browser (Xiaomi devices)
 - Amazon Silk (Kindle/Fire devices)

Updated the detection order to check for Chromium-based browsers BEFORE
checking for Chrome itself. This is critical because Samsung, Yandex,
Vivaldi, UC, MIUI, and Silk all include "Chrome" in their user agent
strings.

Updated is_edge_browser() to detect both:
 - Legacy Edge: "Edge/"
 - Modern Chromium-based Edge: "Edg/"

* Update tests for the new browsers detected

* changelog

* Explicitly test for bacwkard compatibility

Added tests to make sure we fall back to $_SERVER['HTTP_USER_AGENT']
when $user_agent is not passed.

* Add a new private maybe_get_user_agent_from_server method

This is done so that we don't repeat outself so much
