Add option to disable strtolower() in SanitizeStringViewHelper

[No5251]

Add an option to the viewhelper to bypass strtolower().

Do we want to add a general $case parameter, like we have in Format/CaseViewHelper? But then not duplicating all the options? Or how far do we want to go?

I'm not sure what the use case is for case sensitive sanitisation. The ViewHelper was written to write URL slugs/anchors which don't really benefit from case sensitivity. If you could describe a bit about the use case that would help me understand the request or suggest the right approach for your case sensitive use case.

If we add this, it shouldn't be as a general case parameter (since this requires TYPO3 CMS specific classes to handle). If anything we should keep it simple.

Closing due to lack of feedback.
