Andrew Kesterson 18399f2726 Add the vendored dependencies whether or not libakgl is top-level ...

Embedded with add_subdirectory(), the deps/ submodules a recursive clone
just checked out were ignored and find_package(SDL3 REQUIRED) ran instead,
so configure failed on a machine with nothing installed. Each dependency is
now added by akgl_add_vendored_dependency(), which skips it when the target
is already declared or the submodule is missing; the find_package lookups
run afterwards for whatever is left. The CTest suppression moves with them
and is lifted before this project registers its own suites.

Two consequences of the move: pkg-config is only looked for when something
has to come from the system, and the build-tree RPATH keys on whether
anything was vendored rather than on being the top-level project, so an
embedded build's tests can find the satellite libraries too.

Verified by configuring and building a consumer that embeds this repository
with CMAKE_DISABLE_FIND_PACKAGE_* set for all seven dependencies.
