This PR mainly handles all places where InferenceBuilder is used to
access any op or a specific implementation for an op.
Instead an op is defined, and its proper implementation is picked inside
and the usage will be transparent to the user.
What was done in the PR:

  1. Added missing ops (added a py file with fallback mechanism)
  2. Added missing fallback implementations for existing ops
  3. removed all usages for builder.load and replaced them with ops instead.
  4. added workspace op and inferenceContext which contains all workspace related functions and inferenceContext is the python fallback of inferenceContext in CUDA
  5. a small change to softmax_context signature to fit the fallback signature.

Hi @oelayan7 - thanks for the contribution, could you take a look at the failing tests?

Kicked off a manual run of the nv-ds-chat GH workflow since this PR modifies the Hybrid Engine:

@loadams, @jomayeri, FYI.
