Make USB Charging default value configurable per device

A reasonable default assumption for a user
would be that they can plug their device into
a USB AC adapter and it will charge with as much
current as it reasonably can. With the previous
default, an AC adapter will only do 100mA, basically
a trickle charge.

Make this configurable default per-device, so as not
to break old devices without testing.

Define TARGET_USB_CHARGING_DEFAULT to USB_CHARGING_FORCE
to use the new default.

Tested on both erosQ Native and M3K.
