[SDKS, LLVM] Disable detection and use of libxml2 (#11341)
Mono doesn't use libxml2 and neither do the LLVM bits used by Mono when building
the AOT cross-compilers. Presence of `-lxml2` on the command line breaks 32-bit
builds on 64-bit Linux hosts:

Installation of `libxml2-dev` (on Ubuntu/Debian + friends) for the x86
architecture (or x86_64 architecture on 32-bit host) would be possible but then
it would break the 64-bit build because the 64-bit version of the library would
be absent. It would be a problem if Mono+LLVM actually used xml2, but since it
doesn't we can just disable the feature completely.
