Don't emit CA1849 for DbContext methods

[CollinAlpert]

This PR adds exclusions for the DbContext.Add() and DbContext.AddRange() methods and fixes a false negative for IDbContextFactory<DbContext>.CreateDbContext() in the UseAsyncMethodInAsyncContext analyzer.

Fixes #6684.

The build is complaining that there is a missing entry in RulesMissingDocumentation.md for rule CA2200, however documentation does exist for that rule. Is this a bug in the build?

Strange, usually it complains when there is an entry that needs to be removed because the corresponding doc is added.

Anyway, better to run the msbuild /t:pack to see if there were any doc update happened

[CollinAlpert]

I ran that command already and no changes were made, which makes sense. I can try again tomorrow.

Thank you @CollinAlpert!

Do we know if this is already shipped with a .NET8 preview? Or it will land in next one?

[cremor]

Will this only ship with a .NET 8 SDK, or will it also be included in a .NET 7 SDK update?

[buyaa-n]

It should have included in .NET 8 preview 7, it is not ported to .NET 7

[Spacefish]

I get a lot of CA1849 warnings with .NET 8 Preview 7 for my DbSet.Add(..) calls..
As we are not calling the "Add" directly on the DbContext but instead on the Sets on the Contexts.. Maybe we should include that as well.

I created an PR here: #6858
