midi2: host example - simplify and rename to midi2_host

Drop Feather-specific scaffolding (SSD1306 display, font, PIO-USB pin
override) and rename the directory to midi2_host. The example is now a
single main.c + tusb_config.h pair following the midi_rx pattern, with a
printf-only UMP decoder for Channel Voice messages.

Build-tested on adafruit_feather_rp2040_usb_host, daisyseed (stm32h7),
mimxrt1010_evk, stm32f407disco, raspberry_pi_pico2, b_u585i_iot2a,
portenta_c33, stm32h503nucleo, stlinkv3mini, feather_stm32f405.
