Create SDL1 Module

[nhurde]

This module will be for outdated and older devices that do not have SDL2 or SDL3.

This is not a priority, but will be cool for retro systems, handhelds and other devicecs where SDL1 can handle the job. Not a high priority, but is certainly doable when enabling checks if XYZ is supported, slower via software instead of hardware, etc.

There is some older code for this already, but should be updated to be similar to SDL2 and raylib modules.

Not priority for LTS support 1.6X.

SDL1 module should require up to C++17, but being for older systems would be awkward for newer C++ versions (Keep in mind or discussed later as compiler does compile regardless, I believe..)
