(conan-io#18891) openvdb: migrate to Conan v2

* openvdb: migrate to Conan v2

* openvdb: the patch is no longer required

* openvdb: add v8.2.0

Newer versions require considerable amounts of memory to build, probably too much for the CI. More than 1.5 GB per core.

* openvdb: bump deps, use cache_variables

* openvdb: remove broken minimum TBB version check

* openvdb: enable v9, v10, expose all available options, fix imath use

* openvdb: add and disable use_explicit_instantiation to limit memory usage during build

* openvdb: disable options not available in older versions

* openvdb: require flex and bison for build_ax

* openvdb: backport a bugfix for a build issue

* openvdb: bump versions

* openvdb: openexr requires transitive_libs=True

* openvdb: use imath instead of openexr for newer versions

* openvdb: use strict version checking

* openvdb: set use_imath_half=True

To fix
error LNK2001: unresolved external symbol "__declspec(dllimport) private: static unsigned short const * const half::_eLut"
etc on MSVC.

* openvdb: bump deps

* openvdb: add v10.1.0

* openvdb: drop v8.0.1

* openvdb: add v11.0.0

* openvdb: fix C++ standard in test_package

* openvdb: drop v8

* openvdb: enable log4cplus by default, bump deps

* openvdb: deprecation warning for with_exr

* openvdb: disable log4cplus

* openvdb: don't need cache_variables
