Add #[repr(C)] to AllocateType

[LightAndLight]

EFI_ALLOCATE_TYPE is a C enum (https://uefi.org/specs/UEFI/2.10/07_Services_Boot_Services.html?highlight=efi_allocate_type#efi-boot-services-allocatepages), and it's used in protocols such as the PCI Root Bridge I/O protocol (https://uefi.org/specs/UEFI/2.10/14_Protocols_PCI_Bus_Support.html#efi-pci-root-bridge-io-protocol-allocatebuffer).

Would you like me to add this to the changelog?

I don't think a repr is needed here, because this type is never passed directly to/from the firmware. It's used in BootServices::allocate_pages, which matches on the enum value and converts it to raw type and addr values:

uefi-rs/uefi/src/table/boot.rs

Lines 157 to 161 in 9cb1d38

	let (ty, mut addr) = match ty {
	AllocateType::AnyPages => (0, 0),
	AllocateType::MaxAddress(addr) => (1, addr),
	AllocateType::Address(addr) => (2, addr),
	};

You're right. Also, the AllocateBuffer docs say that the type parameter is currently ignored.
