AK: Add SFINAE fallback for AK C++ concepts use, for Coverity compiler The Coverity compiler doesn't support C++2a yet, and thus doesn't even recognize concept keywords. To allow serenity to be built and analyzed on such compilers, add a fallback underdef to perform the same template restriction based on AK::EnableIf<..> meta programming. Note: Coverity does seem to (annoyingly) define __cpp_concepts, even though it doesn't support them, so we need to further check for __COVERITY__ explicitly.

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. :^)
