MT32: Update Munt to 2.0.1-pre

This update uses upstream commit
f88ef828a600ce66d1f730c8fb2a7f580f6f6165.

This update switches to use the new Munt C++ interface, which
will allow ScummVM to link to an external Munt library instead
of requiring it to be built-in in the future. For the moment,
the emulator is still built-in, since it is not available from
most package repositories.

The Munt driver in ScummVM now uses writeSysex instead of the
(now-private) playSysexWithoutFraming, per recommendation from
the Munt team <https://github.com/munt/munt/pull/30>.

This changeset also removes direct modifications that used to be
made to Munt code, to ease future updates. To update Munt code in
the future:

1. Replace all source files in the `softsynth/mt32` directory with
   new files from the upstream `mt32emu/src` directory;
2. Update `config.h` with the correct version number for the new
   version of Munt;
3. Update `module.mk` to add any new source files that need to be
   built.
