plugins: add kernel plugin implementation
Metadata
Current evaluation
Kernel plugin PR to craft-parts closed unmerged; maintainers said it is too snap-specific. Author moved it to Snapcraft as snapcraft#3922, merged and landed on main via snapcraft#4111.
Resolution: closed superseded
Reason: Closed by the author after cmatsuoka and facundobatista (2022-09-25/27) redirected the snap-specific plugin to snapcraft/parts/plugins; the author stated he closed this PR and reimplemented it in snapcore/snapcraft#3922, which was merged (commit 2b0343c08) and landed on main via snapcraft#4111.

Issue body
Adding kernel plugin to build kernel snaps from linux kernel source.
Kernel snap is a specific snap for Ubuntu Core which contains kernel binary, firmware, kernel modules, dtbs, initrd
There are various options usually involved, initrd has to be packaged in a specific way and have certain content.
At the same time, many of the steps are common to all the kernel snaps builds. This plugin is trying to streamline this as make kernel snap build easier.
