Move EOF to the Osaka Fork (#7719)

* Move EOF to the Osaka Fork * Ensure Osaka activations are working * Remove CancunEOF and PragueEOF forks * Move EOF tools to default to Osaka Signed-off-by: Danno Ferrin <danno@numisight.com> * remove eof tests that fail only because of fork Signed-off-by: Danno Ferrin <danno@numisight.com> * Restore CancunEOF * Update unit tests to use "Cancun" as pre-eof fork * Make PC in trace zeroed to start of code section 0 * Update extcall to consider precompiles warm * Add stack checking to CALLF operation Signed-off-by: Danno Ferrin <danno@numisight.com> --------- Signed-off-by: Danno Ferrin <danno@numisight.com> Co-authored-by: Sally MacFarlane <macfarla.github@gmail.com>
