INDY3: Macintosh version uses PC verb GUI with high-res fonts rather than proper Mac GUI

[ATMcashpoint]

The Macintosh version of Indiana Jones and the Last Crusade has high-resolution fonts and a high-res cursor, which ScummVM currently supports if the original executable is in the game directory.

But currently in ScummVM, the verb GUI at the bottom of the screen is displayed as in the PC version. Even if the high-res fonts are enabled, it will just use these high-res fonts as with the PC-style GUI.

However, on original hardware, the Macintosh version of Indy 3 (in English) uses its own special grayscale verb GUI, with boxes around the verbs. The inventory items are set to the right of the verbs, a bit like the floppy versions of Monkey Island 1, though there is also a scrollbar and persistent block highlighting of selected inventory items.

The dialogue trees and Travel verb options also use a grayscale GUI, with boxes around the centered-text dialog lines, and the "Offer an item" and "Throw a punch" options. The "offer an item" interface is similar. (However, the fighting interface retains the PC style interface, albeit with high-res fonts.)

With all the other improvements to support for the Macintosh version of Last Crusade, the GUI should probably be fixed also.

Tested on Windows 10 version 21H1 (build 19043.1237) using ScummVM 2.5.0 (October 1, 2021).
