Bump UEFI disk image size for amd64 to 3.5 GB

Current Kinetic GCE image builds are failing with the following error:

update-initramfs: Generating /boot/initrd.img-5.19.0-1004-gcp
zstd: error 25 : Write error : No space left on device (cannot write compressed block)
E: mkinitramfs failure zstd -q -1 -T0 25

Seems like after `linux-gcp` update from 5.15 to 5.19 `linux-modules` package
has gotten ~40MB larger and with that GCE image builds are over the edge wrt
available disk space in chroot.

Bumped up disk image size for amd64 to 3.5GB to match the sizes used by armhf
and generic images.
