AK+Everywhere: Make StdLibExtras templates less wrapper-y 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. :^)

AK: Add type traits describing supported operations 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.

AK+Everywhere: Disallow constructing Functions from incompatible types 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.

AK+Everywhere: Make StdLibExtras templates less wrapper-y 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. :^)

AK: Add type traits describing supported operations 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.
