ac table-drive BPF extra-code generation away from switches
Replace the large switch in generateExtra with an extraEmitters
registry (map[TracepointKind]extraEmitter) and convert six inner
switch-on-name helpers to table-driven lookups:
- generateExtraMem -> memFieldOverrides table
- generateExtraEventfd -> eventfdFlagsExpr table
- generateExtraTwoFd -> twoFdOverrides + twoFdDefault
- generateExtraPoll -> pollOverrides + pollTimeoutBody(style)
- generateExtraSleep -> sleepTimespecPtr table
- generateExtraKeyctl -> keyctlOverrides table
Adding a new syscall kind or variant now requires only a table
entry instead of editing switch arms with raw C string literals.
Generated BPF C output is behaviorally equivalent; all existing
tests pass unchanged.
