[native] Use correct log functions for std::format to work (#10035)

Context: https://discord.com/channels/732297728826277939/732297837953679412/1361743322586157116

The `Failed to load shared library` message is currently useless,
because of incorrect `std::format` usage:

	I monodroid-assembly: Failed to load shared library '{}'. {}

Review `log_*()` calls and audit `std::format` usage so that we get
the complete messages we expect to see.
