Bump the shrinkwrap base-slim image to 2026.3.0 and update the FVP
binary path to FVP_Base_RevC_AEMvA_11.31_28, exposing Armv9.6/v9.7
hardware features (SVE2 v3, SME2 v3, has_lsfe, f16f32dot/mm, has_b16mm)
for modern kernel testing.
That breaks boot for kernels older than v6.5. They hang early on the
v9.6 model, before any console output: v6.6 boots, v6.1 and v5.15 do
not. The kernel sets up the SVE and SME EL2 traps with the wrong
register on VHE, so it traps and hangs once the v9.6 model turns on
SME2 and SVE2. This was fixed in v6.5 by the hVHE rework, for example
commit 45a3681a10ff ("KVM: arm64: Use the appropriate feature trap
register for SVE at EL2 setup"). v6.1 and v5.15 do not have it and it
cannot be backported cleanly.
Default to Armv9.7. Pass --parameters FVP_ARM_ARCH_VERSION=9.5 to clamp
the model to Armv9.5 so old kernels still boot. The same knob extends
naturally as Arm publishes new versions: gate each new feature on its
own version threshold and let callers select the latest version their
kernel supports.

Update the boot template to base-slim:2026.3.0 and bring the FVP model arguments up to Arm's v9.7 architecture overlay: add has_lsfe, the v9.6 and v9.7 feature flags (has_arm_v9-6, has_arm_v9-7, sve/sme2 version 3, f16 matmul, b16mm) for both clusters, and regenerate the golden refs.
