use RESIZABLE_JSVARS for other boards than linux ?

I got it running this way.
Simple board gives me 2000 vars
Board with additional PSRAM gives me 20000 vars.
@DrAzzy, we could use 65500 here too

ESP32.py

 'variables'                : 2000,
 'variables_psram'          : 20000,
 'variables_mode'           : "malloc",             ESP32 uses malloc

jsvar.h

extern unsigned int jsVarsSize;
