Remove MIDI support from the core's main TinyUSB. MIDI is still supported using the Adafruit TinyUSB library, just like before (the core never did use it). Compile the Pico-SDK using `-Os` Remove unneeded warning in UF2 upload Blink.ino shows a savings of 3.5KB flash and 400 bytes of RAM. For comparison, with this PR blink.ino reports: ```` Sketch uses 49908 bytes (3%) of program storage space. Maximum is 1568768 bytes. Global variables use 7024 bytes (2%) of dynamic memory, leaving 255120 bytes for local variables. Maximum is 262144 bytes. ```` As comparison, using the MBED core blink.ino reports: ```` Sketch uses 78882 bytes (0%) of program storage space. Maximum is 16777216 bytes. Global variables use 42780 bytes (15%) of dynamic memory, leaving 227556 bytes for local variables. Maximum is 270336 bytes. ```` So, with this PR we use **37% less flash** and and **87% less RAM** for simple sketches.
