Work around menu theme regression with 1.4
Eliminate WindowsAppSDK-VersionInfo.cs duplicate source warning
Remove bogus patch number
Support self-contained
Add publish profiles
Disable debug publish optimizations (inner loop)
Remove wapproj cruft

Note: build failing because in Microsoft.WindowsAppSDK.DeploymentManager.CS.targets, the target GenerateDeploymentManagerCS renamed to GenerateBootstrapCS between 1.3 and 1.4. When 1.4 is released, I'll update this PR to use it, which should resolve the build issue.

We should be sure to relnote this. We should also provide a less brittle way of doing this (or move this into our props/targets so that every app who wants the version number can get it easily).

good idea - updated the related WinAppSDK PR to simply use a property for including version info exactly once, before any compilation
