Change libufdt test cases to compare with libfdt
The dtc adds a new function fdt_overlay_apply() to support DTO.
The original libufdt test cases used /include/ trick to compare
the test case result. Change to compare with the result of
fdt_overlay_apply().
Bug: 35495792
Test: run test scripts (see libufdt/tests/README)

Add shell scripts to verify DTO
Add two shell scripts to verify DTO (device tree overlay).
verify_dto_inc.sh uses syntax /include/ to simulate DTO.
verify_dto_ovl.sh uses dtc to compile dts to dtb,
and uses ufdt_overlay_test_app which implemented with libufdt to
apply DTO.
Also modified test code and test cases to use these shell scripts.

Disable warning messages of testing
With new version dtc, running test cases in libufdt will get
some warning messages when compiling overlay DT, such as:
Warning (unit_address_vs_reg): Node /fragment@0 has a unit name,
but no reg property
Avoid to noise the result of testing, add parameter -qq to disable
these warning messages in unit testing.

libufdt: device tree overlay via unflattening FDT
The original version of libdtoverlay is slow in searching for
particular nodes and adding subnodes/properties due to the operations
on flattened device tree (FDT).
`libufdt` builds a real tree structure (named ufdt -- unflattned
device tree) from FDT. In the real tree, we can perform certain
operations (e.g., merge 2 subtrees, search for a node by path) in
almost optimal time complexity with acceptable additional memory usage.
With libufdt, we improve the merging of two dtb files from O(N^2) to
O(N), where N is the number of nodes in the tree.
Bug: 30800619
Test: run test scripts (see libufdt/tests/README)
Test: manually ported libufdt into a bootloader,
checked it can merge a base dtb and a dtbo to generate a final dtb
to boot the device
