hw/misc: Introduce iommu-testdev for bare-metal IOMMU testing
Add a minimal PCI test device designed to exercise IOMMU translation
(such as ARM SMMUv3) without requiring guest firmware or OS. The device
provides MMIO registers to configure and trigger DMA operations with
controllable attributes (security state, address space), enabling
deterministic IOMMU testing.
Key features:
- Bare-metal IOMMU testing via simple MMIO interface
- Configurable DMA attributes for security states and address spaces
- Write-then-read verification pattern with automatic result checking
The device performs a deterministic DMA test pattern: write a known
value (0x12345678) to a configured GVA, read it back, and verify data
integrity. Results are reported through a dedicated result register,
eliminating the need for complex interrupt handling or driver
infrastructure in tests.
This is purely a test device and not intended for production use or
machine realism. It complements existing test infrastructure like
pci-testdev but focuses specifically on IOMMU translation path
validation.

hw/arm/smmuv3: Extract common definitions to smmuv3-common.h
Move register definitions, command enums, and Stream Table Entry (STE) /
Context Descriptor (CD) structure definitions from the internal header
hw/arm/smmuv3-internal.h to a new common header
include/hw/arm/smmuv3-common.h.
This allows other components, such as generic SMMUv3 tests or test devices,
to utilize these definitions without including the specific SMMUv3 device
internal state.

Currently there are some engines that don't support wasm64 (e.g. unsupported

Emscripten's "-sMEMORY64=2" flag still enables 64bit pointers in C code. But
this flag lowers the output binary into wasm32, with limiting the maximum
memory size to 4GB. So QEMU can run on wasm32 engines.
