Copilot was unable to run its full agentic suite in this review.
Adjusts kdump configuration to better support crash testing on very large-memory VMs by scaling crashkernel reservation and timeouts based on total RAM.
Changes:
- Add tiered crashkernel sizing for TB-scale memory.
- Increase vmcore dump timeout for multi-TB systems.
- Increase reboot timeout to account for longer memory initialization on large VMs.

…large memory VMs - Tiered crashkernel allocation: 4G for >8TB, 2G for >4TB, 1G for >1TB RAM - Tiered dump timeout: 4800s for >8TB, 3600s for >4TB, 2400s for >1TB RAM - Tiered reboot timeout: 1200s for >4TB, 900s for >1TB, 600s default - Fixes kdumpcrash_validate_on_cpu415 OSProvisioningTimeout on M416 VMs

Summary
Scale kdump crashkernel reservation, dump timeout, and reboot timeout with tiered thresholds for large memory VMs (>1TB) to prevent OSProvisioningTimeout failures on multi-TB VMs like M416.
