[build.zig] Drop support for 0.11.0 and use more idiomatic build script code (#3927)
* Remove support for 0.11.0, and make build script more idiomatic + remove all 0.11.0 compatibility functions + remove most LazyPath .path variants + I didn't touch emscripten, I don't know if its relative or absolute + change all absolute paths to use .cwd_relative + only use the builder allocator + have local dependencies use the package manager + make adding raygui more flexible + use zig-cache for generated wayland files * Remove support for 0.11.0 in examples/build.zig * update examples further and add clarifying comment on addRaygui
