Ju|<ebo>< is a sample driver of the media decoder framework, that
has a list of hard-coded mp3 streaming stations in a list that can
be changed between using the app rocker.

The functionality has been distributed to:

 - kernel (hardware_version, freertos_sleep)
 - uctx (scope)
 - sys_buttons (new, low-level button access)
 - sys_display (new, low-level display access)

Previously MicroPython would mount LittleFS directly from the partition
by itself, using its own VFS stack.

This reconfigured the VFS layer in MicroPython to use POSIX
open/read/write/etc calls, which are backed by ESP-IDF. Now, instead of
managing (possibly multuple) block devices at different mountpoints,
MicroPython simply passes through all VFS access to the ESP-IDF VFS.

Then, we make the ESP-IDF VFS mount a wear-leveled FAT (backed by the
same partition which previously held LittleFS) onto /.

This is an annoyingly large change, but the gist of it is that we:

1. Move ctx into components/ctx
2. Move uctx into usermodule/mp_uctx.c
3. Split out uctx config into ctx_config.h and share it with the
   simulator.
4. Delete a bunch of unused ctx files
5. Flip some ctx bits for speed.
6. Draw the rest of the owl, ie. implement a dedicated rasterizer task
   in components/st3m.

This moves the badge23-specific hardware/synth modules into usermodule/.
