build: Add wrap file for tinyxml2

Currently local build on the system without tinyxml2 can fail with
the following message:
"""
meson.build:107:8: ERROR: Dependency "tinyxml2" not found, tried
pkgconfig and cmake
"""
Provide "tinyxml2.wrap" file to fix the issue.
The "tinyxml2.wrap" file is copied from the bmcweb repository.
