USB: Add memcpy_from_usbram and update existing memcpy
Previously there was just a memcpy_usbram that copied to
USB packet memory, and no routine to copy out. This adds
the "from" version and renames and improves to "to" version.
The improvement is that the new "to" version correctly
handles unaligned beginning and endings of the region to
be copied. These need to be read/modify/write accesses since
the USB packet ram has to be manipulated in 16-bit chunks.

BUG=None
TEST=make buildall -j
Verify that discovery-stm32f072 still enumerates and communicates
correctly over USB.
