[test] Remove timeout from test runners
...
See https://github.com/harfbuzz/harfbuzz/issues/2707#issuecomment-707744079
This wasn’t inconsistent as well, HB_TEST_SUBSET_FUZZER_TIMEOUT defaulted
to 12 in the test runner, but it was overridden to 50 in meson.build,
and then meson has its own test timeout.

[ENOMEM] don't perform set process operations if the other set is in an error state.
...
Running a process while the other set is in an error state can potentially corrupt this sets map map (for example by overwritting all of the major values with 0).

[meson] Only pass required dependencies to everything
...
Instead of passing dependencies as required we used one giant shared
dependency list containing all dependencies for every library/executable.
While this kinda works, the specified deps are also used for generating
the pkg-config files and this leads to lots of Requires.private and Libs.private
entries which aren't really needed.
This removes the "deps" array and replaces it with a few smaller ones and
makes sure the public libraries only get passed the dependencies actually
needed.
