meta-toolchain: introduce TOOLCHAIN_TARGET_EXCLUDE to uninstall unneeded deps

TOOLCHAIN_TARGET_EXCLUDE is a list of packages to uninstall from the target
portion of meta-toolchain/SDK, which were brought as dependencies, but not
needed in the SDK.
Useful to have only relevant libPKG and PKG-dev packages with libs and headers
installed, while keeping the main PKG package with binaries out.
