[Chromium] Adding Writing direction to the context menu for linux gtk

Adding Writing direction to the context menu for linux gtk.

Blink side change is here https://codereview.chromium.org/66313007/

This CL takes care of the context menu on Linux Gtk. Most of the changes are copied from Writing direction context menu entry implementation on MacOSX. There seems to be no way to change writing direction on Aura. I would like create a separate CL to implement the same on Aura.

PTAL

Linux recently switched off of the Gtk chrome UI onto the Aura chrome UI, so I'm
not sure that there is much point in changing gtk code anymore (I suspect once
Aura settles down it will be deleted).  But Elliot would know much better than
I.

Linux just changed back to gtk for the time being

Mostly lgtm. That said, I give slightly better than even odds of this gtk code
ever shipping. We're still trying to get linux aura turned on for M33.

However, stamping since there's a large chance we'll be in M34 instead.

Just one thing you should change:

https://codereview.chromium.org/73963004/diff/1/content/common/view_messages.h
File content/common/view_messages.h (right):

https://codereview.chromium.org/73963004/diff/1/content/common/view_messages....
content/common/view_messages.h:183: #if defined(OS_MACOSX) || defined(OS_LINUX)
This includes Chrome OS and linux aura. You probably want TOOLKIT_GTK for the
time being.
