Feature/ninja multi presets support

[Jason5480]

In the first CMake presets integration I used Ninja as the default generator for the presets cpp-best-practices/gui_starter_template#175 (comment).
With those changes "Ninja Multi-Config" generator was made as the default. That will have as a result a faster switch time between Debug and Release builds and will also be consistent with the CI that also uses this generator.
P.S. @lefticus this might be useful for the Game Jam! not mandatory though.

@Jason5480 Sorry I didn't see this PR sooner. I'm hoping to continue to extend the presets for consistency with the developer_mode user_mode settings also (so there's a conflict here right now)

We also now have #16 open, if you think you could give a look at that one.

I'm very much not familiar with CMakePresets and just kind of blindly doing things that seem to work.

The PR #16 is ready, and the added functionality is extremely useful. I will rebase based on that!
Now for the developer/user mode I faced some problems on windows that made the cmake configuration hang. Maybe there are some added dependencies I didn't had that caused that, but had no time to dig in.
Just because "mode" is a different concept I would propose creating hidden presets that can be composed with "inherits" list.
What I had in mind is the following:

"name": "mode-user",
"description": "User mode that...",
"hidden": true,
"cacheVariables": {
      "ENABLE_DEVELOPER_MODE": "OFF"
 },
"name": "mode-developer",
"description": "Developer mode that add...",
"hidden": true,
"cacheVariables": {
      "ENABLE_DEVELOPER_MODE": "ON"
 },
...
{
  "name": "windows-msvc-debug-developer-mode",
  "displayName": "msvc Debug (Developer Mode)",
  "description": "Target Windows with the msvc compiler, debug build type",
  "inherits": [
    "conf-windows-common",
    "mode-developer"
  ],
  "cacheVariables": {
       "CMAKE_C_COMPILER": "cl",
       "CMAKE_CXX_COMPILER": "cl",
       "CMAKE_BUILD_TYPE": "Debug"
     }
},

Note the "multiple inheritance" in windows-msvc-debug-developer-mode.
With that approach if you want to change something in the mode logic e.g. making the ENABLE_DEVELOPER_MODE string or adding a new cmake variable you just modify one preset instead of all *-developer-mode presets.
