Change: [Win32] don't allocate 192KiB of memory on the stack on crash (#11240)

Heap is out of the question, as it might be corrupted.
Allocating this much on stack is silly.

So instead, allocate virtual pages to write the information in.

Change: [Win32] unify the crashlog handler with the other OSes (#11236)

While at it, make the crash text a bit more readable, and sync
this with MacOS.

Change: rebrand 1.12.0 to 12.0

One question that keeps popping up: "when do we release 2.0?".
NewGRF will force that at least 1.16 will be 2.0, but to not wait
for this, let's drop the "1." and be for ever done with that
conversation.

We are following in the footstep of giants here.

Add: introduce CMake for project management

CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.

Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.

This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.

Addtiionally, this heavily improves our detection of libraries, etc.
