This series adds semihosting support to hexagon system emulation, together with functional tests for the added operations. The Hexagon semihosting spec can be found at: https://docs.qualcomm.com/doc/80-N2040-101_102648/topic/semihosting-specification.html
Please also update docs/system/target-hexagon.rst to remove "Semihosting is not yet implemented in QEMU hexagon" and add a link to the spec.
