Refactor macOS CI so that tests run in parallel
- Also:
- Fix bootstrap issue where curl was failing for a month (so obviously not needed)
- Change Windows test stages to use PowerShell Core (where we can) to avoid compat issues
## PR Context
This allows running all tests in about the same about of clock time.
Split Windows CI into the following Jobs
1. Combine Build and xUnit, which published build artifact
1. Elevated CI tests
1. Unelevated CI test
1. Elevated everything else tests
1. Unelevated everything else tests
1. Package build and test
1. Verify xUnit result
## PR Context
Before this test:
- A CI run would take ~14 minutes
- A Feature run would take ~30 minutes
After this change, it always runs all tests and takes ~20 minutes.
Job `Unelevated everything else tests` is the long poll, taking ~4 minutes longer than the next shortest job. We should be able to get this back down to ~15 if we split that test job somehow.
Refactor Unified Release Build
- Make injecting the nuget.config a template

- Also, fix an issue where `-workingdirectory` didn't work when running async
- Add VSTS CI for Windows
- Disable `Access-denied test for Get-Item C:\windows\appcompat\Programs\Install -ErrorAction Stop`, because the path does not always exist
- https://github.com/PowerShell/PowerShell/issues/7553
- Disable `Should give .sys file if the fullpath is specified with hidden and force parameter`, because pagefile.sys doesn't always exist and other files don't meet test's requirement.
- https://github.com/PowerShell/PowerShell/issues/7554
- Disable some `Test-Connection` tests for same reasons they failed on VSTS Linux
- https://github.com/PowerShell/PowerShell/issues/7555
- Disable `Test-FileCatalog should pass when catalog is in the same folder as files being tested`, because the CmdLet does not work in that scenario
- Also, give details needed to investigate when the test fails
- https://github.com/PowerShell/PowerShell/issues/7556
- Update `appveyor.psm1` to work with VSTS
- Update `HelpersRemoting.psm1` `New-RemoteSession` to work for CimSession (discovered an issue during the investigation)
- Update `Test wildcard with drive relative directory path` to work when there are multiple drives
- Disable on non-windows machines since the test is assuming drive letters
- Update `New-CimSession` Tests to requireAdmin
- Also, make sure session name is a string
- Add functions to save and restore psoptions
- update `.gitatttributes` so files clone like they do on appveyor
