ci: use reusable workflows from pyTooling/Actions

[umarcor]

In this PR, the CI Pipeline is reworked in order to use reusable workflows from pyTooling/Actions (see pyTooling/Actions#1).

Each job is replaced with a call to a reusable workflow.

As explained in VHDL/pyVHDLModel#36, the logic for dealing with global parameters is changed.

MPORTANT: reusable workflows must be used through an absolute name and specifying a version (see actions/runner#1493). Therefore, this PR will be kept as a draft, because s/@dev/@main/ is required in Pipeline.yml before merging.

pyTooling/Actions#1 is now merged. Do you want to adjust the branch name?

I suggest to use a tag like v0 (while still testing) and then later v1.
What do you think?

See pyTooling/Actions#5.

Ref v0 is available in pyTooling/Actions now. I updated this PR accordingly.

I think this is ready to review and merge.
