[SF.12: Prefer the quoted form of #include for files relative to the including file and the angle bracket form everywhere else](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Rs-incform)
Additionally changed #include order in `span` so that all `span_ext` is in the GSL include block and not in the STL include block.
Fixes issues #1025.

- suppress " warning C26481: Don't use pointer arithmetic. Use span instead (bounds.1)."
- Please note that the suppression in `end()` does not work with MSVC 16.5.4.
VS 2019 doesn't seem to match -1 for size_t template parameter, as a result dynamic span/basic_string_span/basic_zstring_span show extent as `extent = 4294967295` (for 32-bit builds). This change updates details::extent_type to have static constexpr size_ parameter for non-dynamic span/basic_string_span/basic_zstring_span and simplifies/removes dynamic versions from GSL.natvis
