BETA 2 "Th24" build - M126.0.6478.251

IMPORTANT: Please see release notes of previous beta (Beta 1) release, otherwise you will be lost with these notes.

(FYI, when I say "restored", I mean restored to the pre-CR23 UI state).

• Downloads page "X" button fixed
• Minor sizing issues fixed
• Added a new item to the tabstrip right click menu: "New tab to the left" to compliment the default which is "New tab to the right". IDK why they didn't do this upstream, it makes sense, because sometimes you may want to open a tab to the left.
• Number of bookmarks you can open before it prompts "Are you sure you want to open XXX tabs?" was upped from 15 to 50. (Personal pet peeve of mine)
• Theme is "Classic" by default, instead of "Mica" (On Windows), or GTK/QT on Linux. This is to provide a consistent experience as well as prevent an issue where tab separators would be practically invisible. Of course you can still change it to one of those others, and if you have a theme installed, it will not overwrite that.
• Bookmarks bar size adjusted
• InfoBar size restored
• Dialog box/find box/page info box radius restored
• Bug where one could not select a tab if you were not "centered" on the tab, i.e. if you just moved your cursor to the top of the screen above the tab you were trying to select, was fixed after a long debugging session and FaceTime call with @midzer lol. Fixes #804, and partially fixes #640
• Button radius restored (but only for non-WebUI layers, i.e. "native" buttons, so for example, the buttons on the settings page are still bad, while ones on a dialog box for an OS function like printing is restored)
• Volume icon corrected
• Added thorium_2024.h header file to the .patch file so that it would actually work for people wanting to build it for themselves.
• Minor revision updated to .251, which has two security fixes for WebAssembly

TODO: Fix menu padding on Windows, bookmarks bar underline, and folder icons (Note to self: Use .png of 128x128 instead of .icon vector format)

M127 coming soon, which will have a mostly final version of Th24.
