For release notes, see [1] and [2].

The grub2 project moved to gitlab. See [3] and [4].
This commit updates GRUB2_SITE accordingly.

The commit removes the package patches which are included in this
release, and also adds an upstream patch to fix an issue on arm64
platform.

Tested by compiling and booting the defconfigs using grub2:

    qemu_aarch64_sbsa_defconfig
    qemu_arm_ebbr_defconfig
    qemu_loongarch64_virt_efi_defconfig
    qemu_riscv64_virt_efi_defconfig
    qemu_x86_64_efi_defconfig
    pc_x86_64_bios_defconfig
    pc_x86_64_efi_defconfig

and running the runtime tests with:

    support/testing/run-tests \
        -d dl -o output_folder \
            tests.boot.test_grub \
            tests.fs.test_iso9660

Changes v1 -> v2:
- No change.

Note: runtime tests using i386 CPU are failing due to unrelated
reasons (illegal instruction in libc form /sbin/init). Without
this bump, those tests are failing the same way. Since the
failure happens in user space, it means the boot still work with
this bump.
