feat(wifi): Allow setting minimum time for wifi scan

[P-R-O-C-H-Y]

Description of Change

This PR add a function to WiFiScan class for setting the minimum active scan time.
This allows complete timing customisation for Wifi scan.

void setScanActiveMinTime(uint32_t ms);

The default value is 100 to keep compatibility with previous code.

WiFi scan timing parameters explained:

min=0, max=0: scan dwells on each channel for 120 ms.
min>0, max=0: scan dwells on each channel for 120 ms.
min=0, max>0: scan dwells on each channel for max ms.
min>0, max>0: the minimum time the scan dwells on each channel is min ms. If no AP is found during this time frame, the scan switches to the next channel. Otherwise, the scan dwells on the channel for max ms.
