Revert dynamic GLOBAL_PARAMS for reliable template passing (#25461)

What is the motivation for this PR
PR sonic-mgmt#21636 imported GLOBAL_PARAMS to refactor pr_test_template.yml, which caused downstream templates to fail to receive parameters reliably. This aims to make parameter passing stable and predictable by replacing dynamic expansion with explicit parameters.

How did you do it
Reverted dynamic GLOBAL_PARAMS expansion to explicit parameters for reliable template passing.

How did you verify/test it
