Fix Unicode string handling
Linux uses UTF8 but java and MTP both
use UTF16. In a few places, this results
in the top byte of a UTF16 string being
truncated on conversion to UTF8.
Also, the hardcoded UTF to byte serialization
in MtpStringBuffer is incorrect.
Replace it with conversions from std, and
replace usages of MtpString with MtpStringBuffer.
Remove any remaining usages of libutils
and replace them with corresponding std
libraries.
Bug: 70546563
Test: Mtp works, tests pass
Test: file/folder names containing emoji can be transferred to/from
windows

Switch MtpFfsHandle to aio, add control functions.
MtpFfsHandle now uses kaio to handle usb data.
This achieves better performance without using
the endpoint alloc ioctl.
This also allows ep0 events to be handled without
race conditions. Events will also include control
requests, which will allow both host and device
initiated cancellation.

Bug: 36802721
Test: Transfer various size files, run MtpFfsHandleTest
Test: Cancel transfer on Windows
Test: Allow device to cancel transfer on Windows
