Add ODP_PatinaSmbiosDemo driver

[kat-perez]

Re-opens the work from #82 (which was inadvertently closed; GitHub blocks reopen because the original head repo lost its fork relationship with upstream). Rebased onto current main, and addresses @rogurr's review feedback on #82 (SPDX header added to source files).

Description

Adds ODP_PatinaSmbiosDemo — a UEFI DXE driver under uefi/OdpPkg/Drivers/ that publishes an SMBIOS Type 0 (BIOS Information) record using only the native Patina component model: no EFI_SMBIOS_PROTOCOL, no raw buffer construction, no unsafe boilerplate inside the publishing component.

The driver mirrors ODP_RustDxeDemo's file layout (Cargo.toml, README.md, .depex, src/) but consumes the Patina component model via the patina_tianocore bridge crate (= "0.1" from crates.io).

• Impacts functionality? — adds new driver
• Impacts security?
• Breaking change?
• Includes tests? — runtime-verified on QEMU OVMF Q35; no unit tests
• Includes documentation? — README + crate-level docs

How This Was Tested

BUILD_DATE=$(date +%m/%d/%Y) cargo build --target x86_64-unknown-uefi --release produces a PE32+ .efi.

Booted on QEMU + TianoCore OVMF Q35 (/usr/share/OVMF/OVMF_CODE_4M.fd):

BdsDxe: starting Boot0001 ... Sata(0x0,0xFFFF,0x0)
[INFO ] BiosInfoSmbiosPublisher: added Type 0 BIOS info
        (vendor=Acme Inc., version=0.1.0, date=05/07/2026) handle=0x0001

The dispatcher resolves Service<dyn Smbios> from SmbiosProvider, runs BiosInfoSmbiosPublisher, which calls smbios.add_record(&record) and gets handle 0x0001. SMBIOS publication round-trips with no C protocol involved in the publishing component.

Integration Instructions

cd uefi/OdpPkg/Drivers/ODP_PatinaSmbiosDemo
BUILD_DATE=$(date +%m/%d/%Y) cargo build --target x86_64-unknown-uefi --release

Drop the resulting .efi into your platform .fdf:

FILE DRIVER = C74158C9-87BC-448B-86B1-818071938A4C {
  SECTION DXE_DEPEX = <path-to>/OdpPkg/Drivers/ODP_PatinaSmbiosDemo/ODP_PatinaSmbiosDemo.depex
  SECTION PE32      = <path-to>/OdpPkg/Drivers/ODP_PatinaSmbiosDemo/target/x86_64-unknown-uefi/release/ODP_PatinaSmbiosDemo.efi
  SECTION UI        = "ODP_PatinaSmbiosDemo"
}

After booting, Shell> smbiosview -t 0 shows the record with vendor "Acme Inc.".

See uefi/OdpPkg/Drivers/ODP_PatinaSmbiosDemo/README.md for the migration path to a Patina-native DXE core (use impl_component_info! on the same OemPlatform struct from platform.rs — zero source changes to the publishing component).

Closes #78

Pull request overview

Adds a new UEFI DXE demo driver (ODP_PatinaSmbiosDemo) that publishes an SMBIOS Type 0 record using the Patina component/service model via patina_tianocore, plus supporting build/docs assets for integrating the produced .efi into an EDK II .fdf.

Changes:

• Introduces a Patina-component-based SMBIOS Type 0 publisher (BiosInfoSmbiosPublisher) and a minimal TianoCore driver shell using driver_entry!.
• Adds build scaffolding for the new driver (Cargo manifest/lockfile, pinned Rust toolchain, DXE depex).
• Adds documentation and repo-level .gitattributes handling for binary .depex files.
