J. Nick Koston 5e64e3a3d4 [api] Store dump strings in PROGMEM to save RAM on ESP8266 ...

All string literals in api_pb2_dump.cpp (field names, message names,
enum value names) were stored in rodata which occupies RAM on ESP8266.
This meant every API protobuf change appeared as a RAM increase in CI
when using very_verbose logging.

Add append_p() to DumpBuffer for PROGMEM-safe string reading and update
the code generator to wrap all dump string literals with ESPHOME_PSTR().
On non-ESP8266 platforms, these are no-ops with zero overhead.
