ti-cgt-pru: add package for PRU Host toolchain

Browse Source 
TI provides a binary code generation toolchain to develop firmware for
the programmable real-time unit/co-processor found in some SOCs such as
some models in the AM335x line. This toolchain includes C/C++ support
(clpru) rather than just assembler (pasm) supported by the pre-existing
am335x-pru-package [1].  Following the lead of the Yocto meta-ti
layer [2], this package provides a host toolchain suitable for an x86
(or x86_64) Linux targeting an ARM-based PRU core.

[Thomas: add BR2_PACKAGE_HOST_TI_CGT_PRU_ARCH_SUPPORTS boolean option,
so that packages selecting host-ti-cgt-pru can easily inherit its
architecture dependencies.]

This package provides the Code Generation Tools for the PRU
unit found on some TI processors e.g. AM3358.
Note: this is a binary cross toolchain that runs on x86 hosts
targeting PRU cores found alongside some ARM processors.
