devel/simdjson: update to 0.5.0

From ChangeLog: https://github.com/simdjson/simdjson/releases/tag/v0.5.0

Performance

 * Faster and simpler UTF-8 validation with the lookup4 algorithm
 * We improved the performance of simdjson under Visual Studio by about 25%.
   Users will still get better performance with clang-cl (+30%) but the gap
   has been reduced.

Code usability

 * In parse_many, when parsing streams of JSON documetns, we give to the users
   runtime control as to whether threads are used (via the parser.threaded
   attribute).
 * Prefixed public macros to avoid name clashes with other libraries.
 * Better documentation regarding package managers (brew, MSYS2, conan, apt,
   vcpkg, FreeBSD package manager, etc.).
 * Better documentation regarding CMake usage.

Standards

 * We improved standard compliance with respect to both the JSON RFC 8259 and
   JSON Pointer RFC 6901. We added the at_pointer method to nodes for
   standard-compliant JSON Pointer queries. The legacy at(std::string_view)
   method remains but is deprecated since it is not standard-compliant as per
   RFC 6901.
 * We removed computed GOTOs without sacrificing performance thus improving the
   C++ standard compliance (since computed GOTOs are compiler-specific
   extensions).
 * Better support for C++20
