vmm_tests: memory validation CI/CD pipeline tests for main (#1995)
Description: This PR updates the VMM test pipeline to evaluate VTL2 memory usage. This is done to track changes in memory usage and produce a failed test for builds that result in an increase in memory usage beyond reasonable variance. **Changes** - Implement module to collect all relevant VTL2 memory usage information - Add tests for VMs with 2VPs and 64VPs with 16GB VTL0 memory across TDX, SNP, and ARM architectures - Add test for VMs with 2VPs and 32VPs with 16GB VTL0 memory for GP x64 VMs - Log memory usage information as JSON - Produce a failed test for builds that result in memory usage that exceeds reasonable variance from baseline values
