Constants for Matter wildcards (CON-1108)

[jonsmirl]

Please add constants for subscription wildcards -- any-endpoint, any-cluster, any-attrib, etc
in esp-matter-controller

[wqx6]

You could use 0xFFFF for any-endpoint, and 0xFFFFFFFF for any-cluster and any-attribute.

For example,
Read all the attribute in the cluster 0x6 of endpoint 1 on node 1:

matter esp controller read-attr 1 1 6 0xFFFFFFFF

Read all the attributes in all the clusters of endpoint 1 on node 1:

matter esp controller read-attr 1 1 0xFFFFFFFF 0xFFFFFFFF

Read all the attributes in all the clusters of all the endpoints on node 1:

matter esp controller read-attr 1 0xFFFF 0xFFFFFFFF 0xFFFFFFFF

I am using FFFFF... and it works. Please add some constants in the subscribe h file to make this more readable.
const wildcardAttib = 0xFFFFFFFFFFFFFF;

Will add the comment in the header files to declare the wildcards.

Added the comments in the headers. Could we close this issue?
