Adds 1.54" e-ink display (gdew0154m09) support to waveshare_epaper component (#4939)

Browse Source 
* Added GDEW0154M09 in waveshare_epaper component

* noop change - trigger workflow

* Make linter happy

* Update test4.yaml

* linter doing linty things

* revert the newline removal.

* revert to prove unstable test

* add code back into test.

* no partial updates supported yet - removed from test.

* Update esphome/components/waveshare_epaper/waveshare_epaper.cpp
