[release/6.0] Source-build: Allow setting KnownAppHostPack and KnownRuntimePack

[ayakael]

##Source-build: Allow setting KnownAppHostPack and KnownRuntimePack

Description

This should've been in #44752, which was backport of #43937. Without this, we run into unrecognized RID issues in source-build application.

Customer impact

Will be able to build aspnetcore with RIDs that were automatically added in the runtime graph when building with source-build.

Regression?

• Yes
• No

[If yes, specify the version the behavior has regressed from]

Risk

• High
• Medium
• Low

Only activates when PortableBuild=false. As it defaults to true, this change should not affect any other customers than distro maintainers.

Verification

• Manual (required)
• Automated

Packaging changes reviewed?

• Yes
• No
• N/A

Works for me but I don't think the branches are open. @mmitche, @vseanreesermsft❔

This won't succeed for a while. Is the fix urgent❔

This won't succeed for a while. Is the fix urgentgrey_question

Not at all. We already deploy this fix in the Alpine Linux dotnet6 package so the runtime graph gets automatically updated on new releases. I'm upstreaming this as a courtesy.
