[api] Store YAML service names in flash instead of heap
Reduces memory usage for YAML-defined API services by storing service
names and argument names as pointers to string literals in flash instead
of heap-allocated std::string objects.
Implementation:
- Created UserServiceBase<Ts...> for YAML services (const char* storage)
- Created UserServiceDynamic<Ts...> for custom_api_device (std::string storage)
- Updated CustomAPIDeviceService to inherit from UserServiceDynamic
- UserServiceTrigger uses UserServiceBase (YAML-only)
Memory savings per YAML service:
- 0 args: 32 bytes (57% reduction)
- 2 args: 48 bytes (60% reduction)
- 5 args: 96 bytes (63% reduction)
Custom API device services maintain same memory footprint (no regression).
Typical ESPHome device (2-5 services): 100-240 bytes saved
High-service device (10+ services): 400-800 bytes saved
