dev-libs/tinyxml2: drop static-libs USE flag

Upstream collapsed static/shared builds into one target and we don't
have any current users of static-libs in the tree so drop support for it
instead of figuring out how to run configure/build/install twice with
differing settings.

Closes: https://bugs.gentoo.org/673046
