Enforce map-function compatibility checks (#1127)

Add allowed_map_types bitmask to EbpfHelperPrototype, threaded through
CallContract and checked via a new ValidMapType assertion. This encodes
the function→map direction of the kernel's check_map_func_compatibility
(v6.18): each helper that requires specific map types now declares them,
and the checker rejects mismatches at verification time.

Covers 34 helpers across perf_event, ringbuf, storage, redirect, queue/
stack, cgroup, and reuseport families. Map type UNSPEC (0) is treated
as unknown and silently allowed to avoid false positives from incomplete
ELF metadata.

Closes #1123
