Fix: Original music playback rate was slightly too fast

Found a new tempo value experimentally. The new value gives a timing error of less than 0.01 second per minute.

Codechange: replace IConsolePrintF with IConsolePrint and fmt formatting

Also make some strings more consistent with the rest of the console strings.

Codechange: Use std::string in console commands/aliases registration, and std::map instead our sorted linked list (#9057)

* Codechange: Use std::string in console commands and aliases registration

* Codechange: Use std::map to register console commands

* Codechange: Use std::map to register console aliases

* Cleanup: Remove now unused function

Fix: Two issues in MIDI file writer

Variable-length values would write threshold values with a byte too many.
System Exclusive messages would cause write to fail since the end byte was treated as part of next message.

Feature: Decoder for DOS version music

This is based on reverse-engineering the TTD DOS driver for General MIDI music.

Change #6685: Replace Win32 music driver with one not depending on MCI

MCI MIDI is poorly supported on newer versions of Windows and can cause large
delays at the beginning of tracks.

The new driver is based on a from-scratch reader for Standard MIDI Files. This
should be re-usable in other music drivers too, and can allow for finer control
of playback in general.

It also provides a better framework for reading MIDI data from other formats
than just SMF.
