On ESP8266, .rodata is copied to RAM at boot. Every string literal in
HomeAssistantServiceCallAction (service names, data keys, data values)
permanently consumes RAM even though the action may rarely fire.
Add FLASH_STRING type to TemplatableValue that stores PROGMEM pointers
on ESP8266 via the existing __FlashStringHelper* type. At play() time,
strings are copied from flash to temporary std::string storage — safe
because service calls are not in the hot path.
Add FlashStringLiteral codegen helper (cg.FlashStringLiteral) that wraps
strings in ESPHOME_F() — expands to F() on ESP8266 (PROGMEM), plain
string on other platforms (no-op). This helper can be adopted by other
components incrementally.
On non-ESP8266 platforms, FLASH_STRING is never set and all existing
code paths are unchanged.

## Description:
Move esphome-core codebase into esphome (and a bunch of other refactors). See https://github.com/esphome/feature-requests/issues/97
Yes this is a shit ton of work and no there's no way to automate it :( But it will be worth it 👍
Progress:
- Core support (file copy etc): 80%
- Base Abstractions (light, switch): ~50%
- Integrations: ~10%
- Working? Yes, (but only with ported components).
Other refactors:
- Moves all codegen related stuff into a single class: `esphome.codegen` (imported as `cg`)
- Rework coroutine syntax
- Move from `component/platform.py` to `domain/component.py` structure as with HA
- Move all defaults out of C++ and into config validation.
- Remove `make_...` helpers from Application class. Reason: Merge conflicts with every single new integration.
- Pointer Variables are stored globally instead of locally in setup(). Reason: stack size limit.
Future work:
- Rework const.py - Move all `CONF_...` into a conf class (usage `conf.UPDATE_INTERVAL` vs `CONF_UPDATE_INTERVAL`). Reason: Less convoluted import block
- Enable loading from `custom_components` folder.
