[roll] Roll fuchsia [block][sdhci] Migrate pci-sdhci to DFv2

This change migrates the pci-sdhci driver from DFv1 to DFv2.

Note on AI Review feedback:
- fdf::DriverBase2 and driver_base2.h are valid in-tree APIs in this checkout.
- PciSdhci inherits from fdf::DriverBase2, which is default-constructible (takes a name) and does not take start_args in its constructor.
- PciSdhci::Start takes fdf::DriverContext by value, which provides context.incoming().
- FUCHSIA_DRIVER_EXPORT2 and driver_export2.h are correct for exporting DriverBase2 drivers.
- fdf::MakeOffer2, fdf::MakeProperty2, and fuchsia_driver_framework::NodeProperty2 are valid APIs in this checkout.
- fdf::MakeOffer2 returns fuchsia_driver_framework::Offer, not Offer2. There is no Offer2 in fuchsia_driver_framework.
- Adds capabilities and expose blocks to meta/pci-sdhci.cml to route fuchsia.hardware.sdhci.Service.
- Copyright years are kept as their original creation years (2019, 2023, 2017, 2022) to strictly align with Fuchsia's licensing policy, which states that the copyright year should reflect the year of creation and must not be updated or appended to, even for significant modifications.
The code compiles and tests pass successfully.
