Support different windows exe names

[liamcmitchell]

Hi, cool libraries! I bumped into kofi-q/pcsc-mini#13 when packaging pcsc-mini into an electron app. This is my attempt at fixing it.

• bumps zig to latest, i couldn't download the windows binaries for the prev version
• adds a new dynamic win32 runtime option which looks up methods lazily, trying to mimic node-gyp & delay-load behavior
• makes dynamic the default, preserves support for static exe linking
• refactors other source generators to run directly, no need for running through node
• adds GENERATED headers to files, should help anyone stumbling across them
• removes unused file _build/testing.zig
• adds win32-runtime flag and examples:*:build steps for easier testing e.g. zig build examples:add:build -Dtarget=x86_64-windows -Dwin32-runtime=deno
• adds symbols_check step to check latest symbols match git
• adds test_win step to ensure win static and dynamic runtimes compile
• added addRuntimeArchCheck to make sure node/deno/bun tests are only run against expected arch (i had x64 bun trying to load arm64 addons)

I used these changes to rebuild pcsc-mini on macOS and with these packages, successfully interacted with a card reader in my packaged electron app on Windows.

Hi @kofi-q, please let me know if you are interested in these changes and if so, what timeframe you might look at them.

Thanks for taking the time to work on this! Been hoping to get a workaround for this issue for while. Will take a look this weekend and test it out - looks great so far from skimming it
