Update xiao-ir-mate-full.yaml

[Didgeridrew]

What

This is a change to one of the provided ESPHome configurations. This change modifies entity naming to avoid over-long names due to the recently-changed compound name generation behavior in HA and to include device MAC in the device name in case users have more than one similar device.

Why

The original config included the, previously required, use of substitutions like ${friendly_name} to get unique entity names. However, recent changes in ESPHome and HA now add that context automatically and the inclusion of those substitutions makes entity IDs unnecessarily long and repetitive.

How

Removed most instances of the ${friendly_name} substitution.
Changed name_add_mac_suffix to true.
