STM32: USB: use distinct EP buffers

This fixes a race condition when multiple EPs perform transfers at the
same time.

Moreover, reorganize the USB packet memory taking into account only the
allocated endpoints. This allows to reduce the memory reserved for
buffer descriptor table (metadata), and enlarge the "useful" memory that
can be allocated for the real USB transfers (data).
