Add deepseek decode layer test into galaxy-quick

[maksim-tsishkouski-epam]

Ticket

Closes #37737

Problem description

Add galaxy deepseek decoder layer module test to galaxy-quick to be able to detect regression frequently

What's changed

Added test_decoder_block.py test to galaxy-quick. Limited test parameters to only HF weights, decode and prefill-128 to save time (quick-wh-glx-deepseek-module takes ~6m + setup job and runner).

Checklist

• Galaxy quick - CI passes (failed quick-wh-glx-quick is not related to changes)

Pull request overview

Adds a Galaxy DeepSeek decoder-layer unit test into the APC (“all post-commit tests”) workflow so regressions are detected more frequently on mainline CI.

Changes:

• Introduces a reusable post-commit workflow to run models/demos/deepseek_v3/tests/test_decoder_block.py on Galaxy hardware with HF weights.
• Wires the new Galaxy DeepSeek APC job into the existing all-post-commit-workflows.yaml via a new boolean input and conditional job execution.
