* AZStd::basic_string improvements The AZStd::basic_string class has a better implementation of the Short String Optimization, which increases the amount of characters that can be stored in a `basic_string<char>` from 15 characters to 22 characters(not-including null-terminating characters). For a `basic_string<wchar_t>` on Windows the amount of characters that can be stored increases from 7 to 10. Using `basic_string<wchar_t>` on Unix platforms SSO character amount from 3 to 4 characters. An additional benefit is that the size of the AZStd::basic_string class has been reduced from 40 bytes to 32 bytes when using the AZStd::allocator. When using a stateless allocator with no non static data members such as AZStd::stateless_allocator, the size of the AZStd::basic_string is 24 bytes.

A benchmark has also been added to compare the speed swapping two `basic_string` instances by 3 memcpy vs 3 pointer swap operations Speed up string operation when in the iterator overload cases of the `assign`, `append`, `insert` and `replace` function. The code was always performing the logic to copy over a string that is overlapping, without actually checking if the string was overlapping in the first place. Added an `az_builtin_is_constant_evaluated` macro that allows use of the C++20 `std::is_constant_evaluated` feature to determine if an operation is being performed at compile time vs run time. That macro is being used to speed up the char_trait operations at run time, by using the faster standard library functions. For example char_traits::move now uses "memmove" at runtime, instead of a for loop.
