This type is useful, as the sizes will be visible in the compiler error
messages, as they will be part of the template parameters. This is not
possible with a normal static_assert of the sizeof a type.

Also adds a simple-ish test for CommonType.

|
This will allow us to make `Optional`, `Variant`, and possibly other
data structures conditionally trivially constructible, destructible,
copyable or movable based on their type parameters.

Aggregate initialization with brace-enclosed parameters is a
[C++20 feature][1] not yet implemented by Clang. This caused compile
errors if we tried to use the factory functions to create smart pointers
to aggregates.
As a (temporary) fix, [the LWG's previously proposed solution][2] is
implemented by this commit.
Now, wherever it's not possible to direct-initialize, aggregate
initialization is performed.

Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.

This was probably forgotten in the last rewrite, this would make
IsIntegeral<T> not work for floating points.

This commit makes the user-facing StdLibExtras templates and utilities
arguably more nice-looking by removing the need to reach into the
wrapper structs generated by them to get the value/type needed.
The C++ standard library had to invent `_v` and `_t` variants (likely
because of backwards compat), but we don't need to cater to any codebase
except our own, so might as well have good things for free. :^)
