CSharp: Fix regression in VS project type selection

A that target contains only `.cs` sources should be generated as a
`.csproj` project even if it links to non-CSharp static libraries.
The latter case was broken by refactoring in commit v3.12.0-rc1~160^2~7
(remove TargetIsCSharpOnly() and use methods from cmGeneratorTarget,
2018-03-19).  The reason is that the `HasLanguage` method added by
commit v3.12.0-rc1~239^2~6 (cmGeneratorTarget: add HasLanguage() as
wrapper for GetLanguages(), 2018-03-19) enforces its "exclusive" check
on the combined set of source file languages and the link language.
To restore the original `TargetIsCSharpOnly` semantics, update
`HasLanguage` to enforce exclusiveness only on the list of sources.

Fixes: #18239
