[PATCH 3/7] arm-bsp/corstone1000: Add linux-yocto 6.19 kernel recipe

linux-yocto does not currently ship a 6.19 recipe, so add a
meta-arm-bsp linux-yocto_6.19.bb that tracks linux-yocto-dev v6.19/base.

Pin SRCREV_machine to fixed revision to keep builds reproducible.

Update Corstone-1000 to prefer linux-yocto 6.19 and align
the user guide pointers accordingly.
