configure: add --enable-tsan flag + fiber annotations for coroutine-ucontext
We tried running QEMU under tsan in 2016, but tsan's lack of support for
longjmp-based fibers was a blocker:

Fortunately, thread sanitizer gained fiber support in early 2019:

This patch brings tsan support upstream by importing the patch that annotated
QEMU's coroutines as tsan fibers in Android's QEMU fork:

Tested with '--enable-tsan --cc=clang-9 --cxx=clang++-9 --disable-werror'
configure flags.
