Fixes#2952. The testsuite indirectly called strftime() with conversion
specifiers defined only in C99. In MSVCRT this function conforms only to
C89. Only in the updated UCRT this functon provides the functionality of
C99.
* Add support for subsecond printing for std::chrono::duration according to the c++20 standard
* Remove assert test that overflows intmax_t
* * Hopefully fix int64_t to int32_t conversion errors.
* Allow proper Duration::rep type to propagate via template argument deduction
* * Hopefully fix int64_t to int32_t conversion errors.
* Allow proper Duration::rep type to propagate via template argument deduction
* Fix sign conversion (-Wsign-conversion) warning treated as error in num_digits()
* Format chrono.h with clang-format
* Remove extra forward slash in doxygen style comment

* Apply all suggestions from GitHub, except for replacing the utility subsecond_helper class with a function
* * Move logic of handling subseconds from utility class to function with name write_fractional_seconds()
* Revert write(Rep value, int width) function to previous state
* Fix -Wshadow warning
* Remove unsued get_subseconds() function, its logic has been moved to write_fractional_seconds()
* Change comment from lowercase int to uppercase Int
* Simplify test check
* Integrate suggested changes
* Remove static from detail functions, they are no longer member functions of a class and static is unnecessary.
* Change comment from "amount" to "number"

This prevents accidentally writing fmt::format when fmt::print was
intended. Other than running tests, there's not a good use case for
discarding the formatted output.
* Fix unicode test
* Add xchar support to chrono formatter
* Replace strftime with std::time_put
* Add std::locale support to std::tm formatter
* Use predefined names and formats for C-locale
* Performance improvement
* Make locale-independent and C locale formats consistent among platforms
