Global property "ContinueOnError" with value "true" or "ErrorAndContinue" is not respected causing broken intellisense in DTBB

Global property "ContinueOnError" with value "true" or "ErrorAndContinue" is not respected, causing broken Intellisense in solution loaded with DTBB (design-time build batching) on which is default - all projects are loaded in "Misc Files".

We run these targets for DTBB:
"Compile", "CoreCompile", "ResolveReferences", "ResolveProjectReferences", "ResolveAssemblyReferences", "ResolveComReferences", "ResolveNativeReferences", "ResolveSdkReferences", "CollectReferencedNuGetPackages"
And pass "ErrorAndContinue" for global property "ContinueOnError".

**Expected:**
It should continue if error occurs.

**Actual:**
MSBuild immediately fails the submission.

So far we've run into two kinds of scenarios that can cause this (see below).
If we fix this issue, we can avoid all other potential user scenarios.

1. Target missing
Repro: see the repro in this issue https://github.com/Microsoft/msbuild/pull/2764

2. Target fails
Repro: user opens a solution the first time when $(IntermediateOutputPath) does not exist:

Target Name=Compile Project=Microsoft.VisualStudio.Workspace.VSIntegration.csproj
Target Name=GenerateAssemblyInfoFile Project=Microsoft.VisualStudio.Workspace.VSIntegration.csproj
