CMakeLists.txt: make it possible to install tests (#6776)

In cross-compilation contexts, running tests needs to be done on the
target machine, for which assimp was cross-compiled. This is currently
not possible as the unit tests are not installed, and remain inside
the source tree... which is not available on the target platform after
assimp has been installed.

To make it possible to run tests on the target platform, this commit
adds a new ASSIMP_INSTALL_TESTS, which allows to install tests. By
default it is set to OFF, preserving existing behavior.

However, if it is set to ON, then:

- The test/unit binary will be installed as /usr/bin/assimp-unit on
  the target

- The models will be installed in /usr/share/assimp/models and
  /usr/share/assimp-models-nonbsd

- The test/unit binary will be compiled with the right paths to the
  models

On a Buildroot-generated system, this allows to successfully run the
test suite:

```
 Welcome to Buildroot

 # assimp-unit
