dev-libs/libxml2: security bump to 2.0.10, with patches

We bump here to 2.0.10, but include patches up to the upstream commit
c0440868.

The only modifications made between the git repo from upstream and
creation of the patchset tarball were removal of any patches which could
not apply because e.g. they touch files not in the release tarball, or
were applicable just to fuzzing so not useful here, and git could not
apply them anyway.

Let's bump to EAPI 7 too, while we're here, to help out the cross
compilers.

Bug: https://bugs.gentoo.org/710748
Closes: https://bugs.gentoo.org/719088
Closes: https://bugs.gentoo.org/704202
Closes: https://github.com/gentoo/gentoo/pull/16405
