Reduces binary size for esp32, s2 and c3 (espressif#47)
on commit deacf43 sdkconfig modifications to build libraries with compile optimization to size (-Os) keep all the bootloaders with -Os and no boot messages changes max number of sockets from 10 to 16 disables LWIP "Experimental PPP and SLIP" because it adds about 60K to the binary size and it's not used in Arduino on commit a133257 sets WIFI LWIP to try first to allocate from SPIRAM on esp32 (this is esp32s2 default configuration) defines SPIRAM_MALLOC_ALWAYSINTERNAL to 4096 bytes on esp32 (same as default for esp32s2) disables SPIRAM_MALLOC_RESERVE_INTERNAL on both esp32 and esp32s2 to release more RAM to heap Related PRs in Arduino-ESP32: espressif/arduino-esp32#5789 espressif/arduino-esp32#5791 Related issue: espressif/arduino-esp32#5699 espressif/arduino-esp32#5474 espressif/arduino-esp32#5630 espressif/arduino-esp32#5751
