Torsten Rasmussen 2e8868c16e cmake: deprecate BUILD_NO_GAP_FILL and introduce type specific gap fill
Deprecate BUILD_NO_GAP_FILL as it gives a false impression that gap
filling can be disabled in binary files.
Binary files are always gap filled due to the fact they contain no
address information. Only option for binary files is to control the gap
fill pattern. When no gap fill is enabled in binary files, then a
default pattern is used by the tool, which usually is 0x00.

Generally the pattern 0x00 leads to unnecessary flash writes, as a
flash generally contains 0xFF after an erase.
Therefore provide a gap fill pattern Kconfig setting instead, with
default value of 0xFF.

For hex-files, intel hex and s19, then gap filling is generally not
needed but in order to still support cases where gap filling is required
then this commit introduces BUILD_OUTPUT_HEX_GAP_FILL and
BUILD_OUTPUT_S19_GAP_FILL. Both settings are disabled per default.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
