MxDirectDraw functions and structures (#33)

* MxDirectDraw functions and structures

* fix indents, and globals

* fix build, add mxdirectdraw build configuration

* add new files to cmake

* MxDirectDraw: Add code from my PR #19 on main repo

Merging in the missing functions from my pull request for MxDirectDraw on the main repo. Credit to @foxtacles for the GetPrimaryBitDepth function. All match 100% on reccmp except ErrorToString, but the problem there is with the jump table at the end.

* improve match

* improve accuracy

* improve accuracy

* move _countof, impove up to 96.90%

* Update LEGO1/mxdirectdraw.h
