Default BLE_API to all

Browse Source 
Export the full ST gap/gatt/hci/hal/l2cap command set by default instead of
just hci,gatt, so apps built against this SDK get the whole BLE API without
a rebuild. Costs ~9 KB more firmware flash: 788 KB, still 13 free pages to
the full stack. Update the build.sh comments and README (env-var table and
flash-budget table) to mark `all` as the default. Builds clean; all faps
link and resolve.
