* Change route and query fallback semantics
- If the list of route parameters is empty then simple parameters are from query only.
- If the list of route parameters is null then fallback from route to query.
- Added tests.

- Throw exceptions if route parameters are specified via attributes but not declared in the list of route parameters.
- Don't fall back to the query string if the the route parameter is specified.
- Added tests

* Support late bound results
- Add support for object, Task<object> and ValueTask<object> result types. We can detect that pattern and generate calls into a helper that does a bunch of runtime checks for known result types.
- Added tests

Adds support to minimal actions for parameters of type HttpRequest,
HttpResponse, and ClaimsPrincipal to be bound to the values of the
Request, Response and User properties of the HttpContext respectively.

Also cleans up some typos in the RequestDelegateFactory tests.

Addresses #33870.

* Use CultureInfo.Invariant - WIP

* Add unit test and fix tryParse error

* Update TryParseMethodCache and fix build error - WIP

* Refacto TryParseMethodCache

* PR review

* PR review

* Add test for TryParse with CultureInfo.Invariant value

* Detect services based on service provider
- Use IServiceProviderIsService to detect if a parameter is a service.
- As a final fallback, try to detect services from the DI container before falling back to body behavior.

* Produce more efficient TryParse code gen.

* Fix optional string parameter handling

* Remove innerTempSourceString

* Update comments

* Add test cases for IEnumerable<TService>

* fix tests

* Remove form support from minimal APIs

* Add

* MapActionSample -> MinimalSample

* Remove MapActionSample.csproj from Mvc.slnf

This does a big chunk of #30248 while heavily refactoring the RequestDelegateFactory by splitting it out into a bunch of smaller methods.

For part 2 of #30248, a "scalar value type that lives in the System namespace", I went with the alternative of "Something convention-based like the presence of a bool TryParse(string, out T) method" instead. This conventions work for types in any namespace including user-defined types.
