Describe the bug
Several Windows system error codes are not mapped in syserror.cpp

https://github.com/microsoft/STL/blob/main/stl/src/syserror.cpp#L27

The description for each of the errors are as follows:
ERROR_FILENAME_EXCED_RANGE -> The filename or extension is too long.
ERROR_BAD_NET_NAME -> The network name cannot be found.
ERROR_NO_MORE_FILES -> There are no more files.

Command-line test case

std::errc::filename_too_long == std::error_code{ERROR_FILENAME_EXCED_RANGE, std::system_category()}; // false
std::errc::no_such_file_or_directory == std::error_code{ERROR_BAD_NET_NAME, std::system_category()}; // false
std::errc::no_such_file_or_directory == std::error_code{ERROR_NO_MORE_FILES, std::system_category()}; // false

Expected behavior
ERROR_FILENAME_EXCED_RANGE should be mapped to std::errc::filename_too_long (ENAMETOOLONG)
ERROR_BAD_NET_NAME and ERROR_NO_MORE_FILES should be mapped to std::errc::no_such_file_or_directory (ENOENT)
