samples: matter: enable dual-bank dfu config for template on nRF54L15

Internal DFU (dual bank) configuration has not been defined in
sample.yaml, thus additional configuration has been defined.
Internal configuration is an release configuration with enabled
LTO to reduce size as much as possibile.
Additionaly aligned the pm_static for internal configuration.
