Seeding FP64 Cleanup, main branch (2023.03.08.)

[krasznaa]

It's been a hot minute since I would've tried to run the code on the integrated GPU of my laptop. Which quickly lead to:

Running ./bin/traccc_seeding_example_sycl tml_detector/trackml-detector.csv tml_full/ttbar_mu200/ 1
Running on device: Intel(R) Graphics [0x46a6]
terminate called after throwing an instance of 'sycl::_V1::exception'
  what():  Required aspect fp64 is not supported on the device
Aborted (core dumped)

After quite some detective work, I had to make these changes to make the seed finding work without FP64 operations.

Clusterization may, and kalman fitting definitely still contains some FP64 operations. But I'll open different PRs for those.
