[Comgr][hotswap] Add SOPP + SOPC handlers

[tgymnich]

• handle_sopp.cpp — SOP_NoOperand / SOP_Subroutine entries: s_endpgm, s_barrier, s_branch, s_cbranch_*, s_setprio, s_sleep, s_waitcnt family, s_waitcnt_depctr/lgkmcnt/expcnt/vmcnt, plus the gfx1250 s_wait_tensorcnt the VIMAGE handler later defers to.
• handle_sopc.cpp — scalar comparisons (s_cmp_eq_i32 / s_cmp_lt_u64 / s_bitcmp1_b32 / ...) writing to SCC. Mirrors LLVM's AMDGPUInstructions.td:1107 categorisation.

Both handlers are reachable through the in-progress dispatch loop (landing later in Wire raiser dispatcher); the current decode-and-bail raiser does not call them yet, but their TUs land in the OBJECT lib so the dispatcher hook-up in the later commit becomes a no-build-rebuild change.

Lit fixtures for SOPP/SOPC follow with the dispatcher commit since they FileCheck the lifted IR shape, which depends on the dispatcher actually calling these handlers.
