yocto-kernel: add support for creating recipe-space kernel features

Add a yocto-kernel command allowing users to create a recipe-space
kernel feature local to a particular BSP.  The new feature is
subsequently available for the normal feature addition and removal
yocto-kernel commands used with features defined in the meta branch of
linux-yocto kernel repos.

+DESCRIPTION
+    This command creates a new kernel feature from the bare config

+    feature will be created in recipe-space, specifically in either
+    the kernel .bbappend's /files/cfg or /files/features subdirectory,
+    depending on whether or not the feature contains config items only
+    or config items along with patches.  The named feature must end
+    with .scc and must not contain a feature directory to contain the
+    feature (this will be determined automatically), and a feature
+    decription in double-quotes along with a capabilities string
+    (which for the time being can be one of: 'all' or 'board').
