Merge branch 'earlephilhower:master' into master

Moves to just released GCC 14.3

Moves to full-fat printf/scanf because Newlib no longer supports all the
calls libstdc++ requires with the older, smaller, nano-formatted-io option.

Moves to latest SDK develop branch with important float acceleration fixes
for the RP2350, among other updates.

Moves to latest pioasm, picotool develop branches

* SDK was refactored, update the includes
* Rebuild PicoSDK and BearSSL libs
* Update certs in BSSL validation example
* Don't spell check the certs!
* Updated tools with full fat++ newlib printf/scanf

+By default, core1 (the second core) has no non-user written code running on it.
+No interrupts, exceptions, or other background processing is done (but the core
