* All of the code in Source/santa_driver containing the kernel extension
* The SNTDriverManager event provider
* All workflows in our CI related to testing if the driver builds

* Kernel extension-specific build rules
* Renames SNTKernelCommon to SNTCommon
* Driver version output from santactl version
* The [SNTConfigurator EnableSystemExtension] configuration key
