[OE-core] [PATCH] recipeutils: Add get_recipe_upstream_version and get_recipe_pv_without_srcpv functions

[Aníbal Limón]

The get_recipe_upstream_version functions tries to get the current
version of recipe in upstream it uses bb.fetch2 latest_versionstring
method also latest_revision when is SCM.

The get_recipe_pv_without_srcpv discards the SRCPV in SCM's recipe like
git it returns a tuple with the version, prefix and suffix of a PV.
