Fix CMake Install: Find*.cmake Modules

[ax3l]

Install the CMake modules in cmake/ into our install prefix. If we build with external dependencies for LZ4 and ZLIB_NG, then downstream projects will need those Modules to populate our CMake import targets in Blosc2Config.cmake during the find_dependency calls (which are just wrappers for find_package).

Follow-up to #537 and #541.

@FrancescAlted this is ready to go and tested with conda-forge/c-blosc2-feedstock#42 and ADIOS2 as downstream dependency that consumes C-Blosc2 + transitive external dependencies. (My tests in #537 used internally shipped dependencies.)

If you like, after this is merged, maybe we could tag a new patch release and skip 2.10.1 on CF in favor of 2.10.2?
Alternatively, I can show you how to patch these two PRs into conda-forge/c-blosc2-feedstock#42

Oops. Fixed!

Thanks. Let's wait for 2.10.2, which should be released pretty soon.
