Merge develop into main (#304)

## New

- Read property files with `PropertiesFile`
- Support `boot.properties` so the user can specify the launcher app and an optional app to start after the launcher finishes. (see `BootProperties.cpp`)
- Create registry for CPU affinity and update code to make use of it
- `AppRegistration` and `ServiceRegistration` now also ensure that the `/data` directories always exist for all apps
- `Notes` is now the default app for opening text files. `TextViewer` is removed entirely. Created `tt::app::notes::start(path)` function.
- WiFi settings moved from NVS to properties file.
- Specify `*.ap.properties` file on the SD card for automatic WiFi settings import on start-up.
- Added `file::getLock(path)` and `file::withLock(path, function)` to do safe file operations on SD cards

## Improvements

- Update TinyUSB to `1.7.6~1`
- Improved `Boot.cpp` code. General code quality fixes and some restructuring to improve readability.
- `tt::string` functionality improvements
- Rename `AppRegistry` to `AppRegistration`
- Rename `ServiceRegistry` to `ServiceRegistration`
- Cleanup in `Notes.cpp`
- `FileTest.cpp` fix for PC
- Created `TestFile` helper class for tests, which automatically deletes files after the test.
- Renamed `Partitions.h` to `MountPoints.h`
- Created `std::string getMountPoints()` function for easy re-use
- Other code quality improvements
- `SdCardDevice`'s `getState()` and `isMounted()` now have a timeout argument

## Fixes

- ELF loading now has a lock so to avoid a bug when 2 ELF apps are loaded in parallel
