* fixed NoSuchMethod caused by mismatched signatures of the "invoke" method generated for lambda arguments
* added test cases in invoke.kt for KFunction and anonymous functions
* added a transformer to wrap the last expression in the bodies of lambdas with return
See KT-35849.
1. When expected lambda return type is a type parameter, don't generate
introduce implicit casts (even if the corresponding type parameter has
an upper bound that would otherwise require such cast).
2. Do not generate implicit null check for lambda return value of
@EnhancedNullability type.
It uses the same logic as an old back-end
(see SamType#createByValueParameter and genericSamProjectedOut.kt),
split into two parts:
1. When inserting SAM casts, use SamType#createByValueParamerer to get
the target SAM type.
2. When inserting implicit casts, cast SAM conversions as arguments of
methods of out-projected types to the original type of value parameter
instead of 'Nothing'.
'descriptor -> descriptor.original' relation is often inconsistent
wrt 'containingDeclaration', parameters, and type parameters,
we have to introduce some workarounds here.
If new inference is enabled only for IDE analysis, then this feature
will be disabled to reduce difference between new and old inference,
but if new inference is enabled in the compiler, then this feature
will be enabled too to preserve behavior of new inference for
compilation

Most of these tests used this directive as a way to opt in to a new
language feature, and most of those features are already stable for a
long time, so no opt-in is needed. Some other tests used the directive
to opt out from a language feature, replace those by the `LANGUAGE`
directive. One test used the directive to test behavior that actually
depended on the API version; use `API_VERSION` directive there instead.
The implementation is a bit obscure because this worked on JS since
Kotlin 1.0 and we should not break that; however, on JVM, a diagnostic
will be reported with old language/API version

Probably, when NI is there this fix will become unnecessary because
there will be no approximation applied, thus the value parameter
will remain Hello<#Captured> instead of Nothing
#KT-17171 Fixed
