Fix debugger visualizer for Ext=gsl::dynamic_extent

Browse Source 
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

fixes #856
