perf trace beauty: Add syscalltbl.sh generating all system call tables

2025-03-21T05:58:08Z

Rather than generating individual syscall header files generate a single trace/beauty/generated/syscalltbl.c. In a syscalltbls array have references to each architectures tables along with the corresponding e_machine. When the 32-bit or 64-bit table is ambiguous, match the perf binary's type. For ARM32 don't use the arm64 32-bit table which is smaller. EM_NONE is present for is no machine matches. Conditionally compile the tables, only having the appropriate 32 and 64-bit table. If ALL_SYSCALLTBL is defined all tables can be compiled. Add comment for noreturn column suggested by Arnd Bergmann: https://lore.kernel.org/lkml/d47c35dd-9c52-48e7-a00d-135572f11fbb@app.fastmail.com/ and added in commit 9142be9e6443 ("x86/syscall: Mark exit[_group] syscall handlers __noreturn").
