Update build system for Linux, macOS, overhaul GitHub Actions, remove serial driver

[garrettsummerfi3ld]

This PR introduces a number of changes to the build system and GitHub Actions workflows, as well as removing the unused serial driver.

• Overhauled GitHub Actions workflows to include Linux, macOS platforms, alongside concurrency for builds and split larger steps into smaller steps for legibility and debugging of failing actions.
  • New runners include X86, ARM32, and ARM64 Linux runners, macOS runners compiling universal binaries alongside the existing Windows runner. ARM runners are using a WPI provided Docker container to build against.
  • Added special rulesets for workflow concurrency for jobs running in sync and queueing builds for branches.
  • Added special rulesets for allowing all branches to run actions instead of only main and PRs to main for testing builds on multiple platforms before a PR.
  • Split apart larger tasks into smaller tasks for better verbosity during workflow runs.
  • Updated action dependencies to latest as older actions are deprecated due to old Node.js runtimes.
  • Restructure how artifacts are created, where instead of a single large artifact including CANBridge binaries and WPILib headers, it is now separated into its own artifact as the headers are universal across all platforms.
  • Cleaned up release workflow for pushing tags to create a draft release where instead of using the GitHub CLI, a dedicated action is used instead for simplicity.
• Updated GoogleTest to fix an issue with macOS utilizing incorrect platform from the WPILib Artifactory. This would fail macOS builds completely.
• Added IOKit linker args for macOS builds to use with the serial driver.
• Removed Windows-only preprocessor macros on the serial driver for all platforms.
• Removed serial driver completely. This driver was not used, nor supported or maintained.
• Add GitHub Dependabot to automate updating GitHub Actions.

There are some changes made in this PR that breaks builds for node-can-bridge, plans to update build and CI for node-can-bridge are underway to incorporate Linux and macOS builds for future releases.

Thanks for making this (at first glance) so much easier to review! Going to try to get to this this week.
