Update 1ES pool tags and restrict to UseScaleSet=true

[Copilot]

Migrates GitHub Actions workflows using 1ES pools to utilize scale set infrastructure. The pools are restricted to require "UseScaleSet=true" while removing extraneous labels such as JobId to comply with pool tagging rules.

Workflow Agent Pool Tag Updates

• Added UseScaleSet=true: Added VMSS tag requirement across all 1ES pools to enable elastic scalability.
• Removed JobId: Removed the JobId tag from all self-hosted runner pools to restrict execution to standard 1ES configuration labels.
• YAML Formatting: Formatted runner configurations inline for consistent structure.

Configuration Example

# Before
runs-on:
  [
    self-hosted,
    1ES.Pool=gha-vmss-d16av5-ci,
    "JobId=ci_build_tidy-${{ github.run_id }}-${{ github.run_number }}-${{ github.run_attempt }}",
  ]

# After
runs-on: [self-hosted, 1ES.Pool=gha-vmss-d16av5-ci, "UseScaleSet=true"]

The tag mentioned in the docs is a tag on the Azure Resources. I've applied that, and correct the label style in this PR, but still no dice.

The tagging on the Azure resources appears insufficient (this PR is still stalled), and has potentially contributed to flakiness in all of our other CI runs. Hard to be sure, but I've removed the tags for now. Suggest we revisit this if and when it's a priority, and we have a clean baseline to test from.
