devtool: deploy-target: Support stripped libs and execs

New devtool deploy-target option --strip which enables deploying
stripped binaries, saving some space on target.

* Copies the files of ${D} into a new directory and strips them in place
* Used oe.package.strip_execs for stripping directory
* Added devtool.conf option "strip" for changing default behavior

Config example:
[Deploy]
strip = true

[YOCTO #11227]
