package/microchip-hss-payload-generator: new package

The Buildroot icicle kit configuration uses the Hart Software
Service's (HSS) payload generator tool. This tool creates a formatted
payload image for the HSS zero-stage bootloader on PolarFire SoC,
given a configuration file and a set of ELF binaries. The
configuration file is used to map the ELF binaries or binary blobs to
the individual application harts (U54s). Add the HSS payload generator
as a host package to support this.
