Like in `FileOpen()` interpret filenames starting with `/` as paths
relative to the current working directory by removing the first `/` from
the path.

`SpiNorFlash.h` is a C++ header, but the `Identification` struct is
created in a C style using `typedef struct`. Clang issues a warining
about this discrepancy:
```

The easy fix is to use a C++ style struct.
Same fix as in: https://github.com/InfiniTimeOrg/InfiniTime/pull/1046
The lv_drivers provided monitor driver supports a `MONITOR_ZOOM`-factor
which scales the window by the set factor. This is 'useful when
simulating small screens'.
The zoom can be set as cmake configuration setting `-DMONITOR_ZOOM=1`.
Probably even more usefull for high-dpi screens where 240 pixels is
really tiny.
Implement the missing functions `xTimerGetExpiryTime()` and `xTimerIsActive()`
for the move of `TimerController` to use FreeRTOS timers.
In the process also fix a slight inaccuracy in the ms to ticks
conversion (no conversion was done as 1000 was close enough to 1024 for
a first working implementation).
