Expand CI System to Build for Mac x86-64 and Windows x86-64

[IntegerLimit]

This PR expands on the base CI System implemented in #148, #174, and #175. This PR adds the compilation and architecture test for both Windows x86-64 and Mac x86-64. As Github Actions has not yet added support for Windows ARM, that is not included in this PR. The file has also been renamed to a more descriptive name (build.yaml vs ci.yaml)

This serves two functions:

1. As a rough guide for other users compiling on those systems
2. As a stepping stone for more robust CI/CD in the future, incorporating builds for all architectures, and those compiled files being uploaded as Action Artefacts, or as Release Binaries.

I have also made the CI System cancel if a second commit is pushed before the task finishes, which is especially important here given the long compile time of Linux ARM (~46 Minutes).

The patch looks very good, thanks! However, can you rename the file back to ci.yaml? (I think that is the standard for continuous integration thing).
