Because Source Highlight will throw an exception if the language is

Remove the TUI execution info window
The TUI execution info window is unusual in that it is always linked
to a source or disassembly window. Even updates of its content are
handled by the source window, so it really has no life of its own.
This patch removes this window entirely and puts its functionality
directly into the source window. This simplifies the code somewhat.
This is a user-visible change, because now the box around the source
(or disassembly) window encloses the execution info as well. I
consider this an improvement as well, though.
Note that this patch caused ncurses to start emitting the "CSI Z"
sequence, so I've added this to the test suite terminal
implementation.

TUI window resize should not need invisibility
When resizing a window, the TUI currently first makes it invisible,
then changes the size, and then restores its visibility.
I think this is done because curses doesn't truly support resizing a
window -- there is a "wresize" extension, but the man page says it
isn't available in all versions of curses.
First, this is probably not a major problem any more. I imagine most
of those old systems are gone now.
Second, I think it's a better API to have this detail hidden inside of
the resize method.
This patch changes the code to follow this idea, and changes the
ordinary resize method to use wresize when it is available. The
special case for the command window is also moved to methods on the
command window.

Turn tui_show_exec_info_content into a method
This changes tui_show_exec_info_content to be a method on
tui_source_window_base. As it is only called by other methods on this
class, it can be private.

Move code to tui-winsource.h
This moves code related to the execution info window from tui-data.h
to tui-winsource.h. It fits better here because the execution info is
conceptually part of the source and disassembly windows, and
tui-winsource.h is where this common class lives.
