u-boot-zynq-scr: reworking boot.scr recipe to work for zynq and zynqmp

Separating out sample boot.cmd file for the three supported arch (zynq,
zynqmp, versal), Updating devicetree, kernel, ramdisk load addresses for
zynq, and dynamically setting DEVICE_TREE_NAME to either system.dtb or
kernel dtb, depending on if dtg is used or not.

This u-boot-zynq-scr implementation is put in to set the default boot
and boot quicker than having to wait for the distro_bootcmd to cycle to
the correct boot medium. For example, zynq arch has boot_targets set to
"mmc mmc0 qspi usb0 pxe dhcp xilinx" and it takes about 30 seconds to
try the 'xilinx' target which will run the correct bootargs.

To use the boot.scr file, zynqmp boards must have BOOT.bin, Image,
system.dtb, and boot.scr in the boot partition and a rootfs extracted in
the second partition. Zynq boards must have BOOT.bin, uImage,
system.dtb, boot.scr, and uramdisk.image.gz in the boot partition.
(uramdisk.image.gz is the ${IMAGE}.cpio.gz.u-boot in deploy directory)

Adding u-boot-zynq-scr dependency to all zynq and zynqmp machine confs.
Conditionally adding system.dtb to IMAGE_BOOT_FILES for zcu102 to
support boot.scr in qemu flow.
