Add Support for Heterogeneous GPU Configurations in the Cuda Component

[Treece-Burgess]

Pull Request Description

This PR adds support for heterogeneous gpu configurations. As a consequence the following were also updated:

• How we internally handle the default device id
• How we handle creating a context for users if one is not provided

Tested on Leconte (8 * V100) and Hexane (1 * V100 & 1 * H100):

I have tested this PR on two configurations:

• V100+A100
• V100+H100

I monitored accurate counts of FP32 and FP64 events on both systems.

Tested and worked as expected.

• A100
• H100
  I noticed one minor error in cuptic_ctxarr_update_current and have one suggestion regarding initializing the hash table.
