Add expected installer return codes

[florelis]

Adding expected return codes for installer. Expected return codes are translated to specific HResults when found and show a custom error message.

• Updated v1.1 manifest schema with new field for expected return codes. Updated file would look like this:

Installers: 
    - InstallerUrl: https://example.com
      InstallerType: exe
      ExpectedReturnCodes:
          PackageInUse: 1
          InstallInProgress: 2

• Updated manifest parsing and validation for the new fields.
• Refactored common code for checking installer exit code from MSI and ShellExecute installs into a workflow task that now also checks the expected return codes.

We need to make sure we have the full set of cases covered; "reboot required" being missing suggests that we have some to get still.

Also, the arguably more important part of this change is having a healthy set of default values per installer type and thorough thought put into how those would be overridden by the manifest. Requiring every MSI to output the fairly standardized set of values is not helpful.

This also plays into my comment on MSIX, as we can normalize the HRESULT returns from deployment into the set of values that we have here to make all package types easier to work with in a uniform fashion.

Updated with default values per installer type.
I changed the way this is represented in the manifest because I hadn't considered multiple return codes mapping to the same response. The format is now

      ExpectedReturnCodes:
          - InstallerReturnCode: 1
            ReturnResponse: PackageInUse
