* Correct `$(SharedFxVersion)` and `$(TargetingPackVersion)` values
- Ensure `$(SharedFxVersion)` doesn't change in `$(NoSemVer20)` projects
- Ignore current project's `$(VersionSuffix)` in `$(TargetingPackVersion)`
- Never assume `$(AspNetCoreBaselineVersion)` matches released targeting pack
- Stabilize both versions correctly
- Use these properties more widely
- Remove other mechanisms to get the same values
- Reduce use of the `_GetPackageVersionInfo` target
- Reduce use of `$(SharedFxVersion)` for the targeting pack
nits:
- Correct comments about old RTMVersions.csproj project
- Fix or remove a few other comments
* Do not pass package filenames on Helix command Lines
- remove parsing of these command-line arguments from `RuntestOptions`
- instead craft the names using passed `$(SharedFxVersion)`
- restore `$(DotNetRuntimeSourceFeedKey)` on Helix command line
- lost somewhere along the line
- correct argument count in runtests.sh
- treated 11th argument as both Helix timeout and feed credential
- count was messed up somewhere alone the line
nits:
- update C# syntax in `RuntestOptions` e.g. remove unused `public` setters
- sort and group properties and their assignments
