MSBuild server dogfooding and release plan

We have evidence from manual testing builds with server enabled builds projects without issues in terms of correctness #13896
Until we were forced to disable it by a regression in 10.0.3xx it was also being dogfooded via aspire in 10.0.1xx and 10.0.2xx.

In terms of performance we were blocked by Restore workaround.
Restore fix was merged to VMR 07-09
Reaction in msbuild https://github.com/dotnet/msbuild/pull/14297 is required and expected to land in daily dotnet 07-10

Next steps:
1. Re-test that restore issue disappeared and performance is improved as expected locally
2. flip the default in sdk
3. write an email for partners to try daily net11
4. Code complete for P7 is 07-16, then we have ~11 days for daily build users to revert if early negative feedback
5. if this does not produce blocking issues it will release in P7.
6. if that does not produce blocking issues it will go to RCs ...
