File locking and DevelopmentService improvements (#358)

- Moved `file::getlock(path)` from `Tactility` to `TactilityCore`
- Changed all existing `file::*` functions to implement locking by default
- Removed all manual locking where `file::*` functions were used
- When `DevelopmentService` receives a file, it doesn't try to allocate it all in memory. This fixes going out-of-memory on devices without PSRAM.
- Fix for TactilityC include

Tactility/Source/i18n/TextResources.cpp
