* Patch eap.o memory leak
WiFi Enterprise option can leak up to 3 allocations per connect/disconnect
cycle: anonymous Identity, password, and some unidentified allocation.
This solution patches eap.o from libwpa2 to call a special 2 part
wrapper instead of vPortFree for cleanup.
Corrected typos and adjusted tabs in script.
Added script eval_fix_sdks.sh to aid in evaluating similarity between
patch sections of .o files being patched across different SDKs.
* Add some dev debug code and improve comments

Fixes: #8082
This patches the callx0 instruction to a nop in eap.o which is part of libwpa2.a.
It looks like espressif fixed the Bug in newer SDK versions, so if we update to the latest NONOS-SDK it is most likely not necessary to add/adapt this patch.
Also modifies the fix_sdk_libs.sh script as it even changed files if no changes were necessary, for example adding multiple system_func1 exports.

This commit allows switching SDK firmware:
nonos-sdk-pre-v3 shipped with release 2.5.0 has issues:
* Some boards show erratic behavior (radio connection is quickly lost), with an unknown cause.
These boards work well with previous nonos-sdk-2.2.1 firmware (#5736)
* Overall performances seem to have decreased (#5513)
This PR restores sdk2.2.1 (as in core-2.4.2).
SDK-pre-3.0 - which has brought long awaited fixes (WiFi sleep modes) - is still available through a menu option available only with generic board.
BREAKING
* new define `-DNONOSDK221=1` or `-DNONOSDK3V0=1`
* for external build systems: new library directory: `tools/sdk/lib/<version>/lib`
* PIO: variable `PIO_FRAMEWORK_ARDUINO_ESPRESSIF_SDK3` is needed for sdk-pre-v3.
Fix#5736
