west.yml: Update zcbor to v. 0.5.1

lwm2m: Regenerate lwm2m_senml code from the CDDL description.
Reapply manual changes.
Create a sh script to perform the regeneration.

tests: zcbor_bulk: Adapt to zcbor 0.5.1
zcbor_new_decode_state() now has no return value.

 The CDDL description is based on the RFC 8428 - Sensor Measurement Lists (SenML). For further
 details please see the chapter 11 - CDDL.
 
 To generate the encoder and decoder:
 
 ```console
-zcbor --default-max-qty 99 -c CDDL_FILE code -e -t lwm2m_senml --oc lwm2m_senml_cbor_encode.c --oh lwm2m_senml_cbor_encode.h
-zcbor --default-max-qty 99 -c CDDL_FILE code -d -t lwm2m_senml --oc lwm2m_senml_cbor_decode.c --oh lwm2m_senml_cbor_decode.h
+sh lwm2m_senml_cbor_regenerate.sh
+```
+
+The above command also applies the lwm2m_senml_cbor.patch patch file.
+If the patch fails to apply, you can attempt to use the 3-way merge capabilities by committing the un-patched changes (i.e. up to and including the clang-format), and the running
+
+```console
+git am -3 < lwm2m_senml_cbor.patch
+```
+
+The patch was created by, committing the unpatched changes, then committing the desired patches in a subsequent commit, then creating the patch file with the command
+
+```console
+git format-patch --stdout HEAD~1.. > lwm2m_senml_cbor.patch
 ```
 
 The default value of the number of maximum allowed records doesn't really matter as it's replaced
 with a Kconfig option.
