Handle Call builtins: fix handling of Falco tests  (#1025)

* falco: fix raw_tracepoint privilege and group expected failures

Mark raw_tracepoint/raw_tracepoint_writable as privileged program types so Falco raw-tracepoint sections are not treated as unprivileged argument checks.

Update Falco sample matrix to move now-passing sections out of TEST_SECTION_FAIL and group the remaining expected failures by root-cause class (offset lower-bound loss vs size lower-bound loss at correlated joins).

* elf/unmarshal: gate builtin relocations via platform call model

Add platform hooks to resolve builtin symbols and provide builtin call contracts, thread relocation-gated builtin call offsets through ProgramInfo, and only treat static helper IDs as builtins at gated call sites.

Also extend platform-table, marshal, and YAML-platform tests to cover builtin resolver wiring and call unmarshal behavior.
* crab: canonicalize unsigned intervals in bitwise_and
When uvalue intervals temporarily carry signed lower bounds (e.g. after joins), Interval::bitwise_and asserted in debug builds. Canonicalize both operands via zero_extend(64) before unsigned bitwise reasoning, preserving soundness and avoiding debug aborts.

Validated by reproducing SIGABRT on reverted code in [falco][verify] and confirming the patched build completes with expected 73 pass / 20 failed-as-expected.

* Fix unsound bitwise_and case for non-singleton all-ones rhs
