Minimum OS Support

[codefiesta]

Description

In order to support developers who are still supporting older operating systems, xcode, and swift compilers this release downgrades the minimum

• Drops minimum operating system versions to the following:
  • macOS 15.0
  • iOS 17.0
  • tvOS 18.0
  • visionOS 1.0
  • watchOS 10.0
• Dropped the minimum swift tools version needed to build the package back down to 6.1.
• Introduced private task method that supports 26 task APIs and falls back to old task APIs when not available.
• Removed the CodeQL workflow as Github doesn't seem to like it's runner usage and consistently disables it.

Developer Notes

As a developer, the minimum requirements to build this package should now be running macOS Sequoia 15.2 using Xcode 16.3 or later. It is possible to download Xcode with Swift 6.1+ compilers for earlier macOS operating systems, however the feasibility of testing becomes a net negative win and developers should test their code thoroughly. See the matrix here for supported Xcode and Swift Compilers.

@vladimirleonidovich - it would be useful if you could test this across all of your old devices before this gets merged. Thanks!
