loader: Implement .hex file loader
This patch adds Intel Hexadecimal Object File format support to the
generic loader device. The file format specification is available here:
http://www.piclist.com/techref/fileext/hex/intel.htm
This file format is often used with microcontrollers such as the
micro:bit, Arduino, STM32, etc. Users expect to be able to run .hex
files directly with without first converting them to ELF. Most
micro:bit code is developed in web-based IDEs without direct user access
to binutils so it is important for QEMU to handle this file format
natively.
