Xcode: Fix framework search paths in STATIC library targets (#14191)

In commit 2bc22bda (Xcode: Add frameworks search paths from link
dependeny closure, 2012-12-07) we made framework search paths from the
link closure conditional on target type, skipping it on STATIC and
OBJECT library targets that do not actually link.  However, the
framework search paths also influence the compile lines (-F options) so
we need them for all target types.  The Makefile generator already does
this, as did the Xcode generator prior to the above-mentioned commit.
