action: simplify the action logic
1. Split the Download and Install phase 2. Add an explicit option to select the "ParameterSet" for the toolchain source. 3. Inline the (now) single use functions. There is no need to have the ceremony around the function definition and invocation. 4. Specialise the install rules for the particular type of installer shipped for the Swift toolchain. It is unlikely to go to a MSI based installer. 5. Update Ubuntu version support for 24.04 6. Clean up some of the test rules, updating to 2025-02-24-a. This work prepares the composite action to integrate actions/cache to use the tool cache to amortize the cost of the download of the installer. This becomes more important as the installer size increases.
