Support building of loadtest apps with locally installed dependencies (#799)

to allow building on Windows arm64 without adding more binaries to
`other_lib`.

* Rationalize include file search directories for appfwSDL, GLAppSDL
   and glloadtests.
* Set up to build loadtest apps for arm64 in Windows CI. Disabled
   because the Windows SDK chosen by CMake does not contain a
   needed library and I have yet to find a way to force selection of
   the latest SDK which does include it.
* Set up x86_64 macOS CI builds to use Brew-installed dependencies.

Other items emerged during this work.

* Fix Windows' loadtest apps to find their resources when run.
* Fix inability to debug libktx on Windows caused by both `ktx.exe`
  and `ktx.dll` trying to use `ktx.pdb`.
* Fix syntax error in tag selection in Actions .yml files.
