Update to latest zig 0.12.0dev while keeping 0.11.0 compatibility

[freakmangd]

The recent 0.12.0dev update caused some breakage in the build system.

This method does require the use of anytype, but the argument name and type checks should make it obvious what type it expects. This should not break any existing code.

Tested on linux with zig 0.12.0dev and 0.11.0

raylib$ zig build
raylib$ zigup run 0.11.0 build
raylib$ cd examples/
raylib/examples$ zig build
raylib/examples$ zigup run 0.11.0 build

Once 0.12.0 is released we can remove all of these compatibility functions
