linux-raspberrypi: Add 4.19 for Raspberry Pi 4
Add recipe for Linux kernel 4.19 for Raspberry Pi 4 and keep 4.14 for Raspberry Pi 3. The recipe for 4.19 is backported from master branch of the upstream of meta-raspberrypi.

+ #
+ # - In devtool builds, externalsrc.bbclass gets inherited and sets a list of
+ # SRCTREECOVEREDTASKS, which don't get run because they affect the source
+ # tree and, when using devtool, we want the developer's changes to be the
+ # single source of truth. kernel-yocto.bbclass adds do_kernel_configme to
+ # SRCTREECOVEREDTASKS, so it doesn't run in a devtool build., In a normal
+ # non-devtool build, do_kernel_configme creates ${B}.config.
+ #
+ # - Normally (e.g. in linux-yocto), it would be OK that do_kernel_configme
+ # doesn't run, because the first few lines of do_configure in kernel.bbclass
+ # populate ${B}.config from either ${S}.config (if it exists) for custom
+ # developer changes, or otherwise from ${WORDIR}/defconfig.
+ #
+ # - In linux-raspberrypi, we add do_configure_prepend, which tweaks
+ # ${B}.config. Since this runs *before* the kernel.bbclass do_configure,
+ # ${B}.config doesn't yet exist and we hit an error. Thus we need to move
+ # the logic from do_configure up to before our do_configure_prepend. Because
+ # we are copying only a portion of do_configure and not the whole thing,
