[yocto] [RFC v1 4/5] plugins/sdk.ide: Update projects affected by changes of a target profile

[Timo Mueller]

From: Timo Mueller <timo.mueller at bmw-carit.de>

If a target profile is modified, renamed or deleted globally the
projects using this profile are updated accordingly.
On deletion of a target profile the affected projects will set use the
standard target profile.
