libSceJobManager technical debt

sce::Job::JobManager (libSceJobManager) is written from the disassembly of the copies PPSA01474 and PPSA36082 ship in sce_module, and guest_job_manager_tests passes against both of those modules as well: the memory size formula, the error codes, sync point ordering, the per-sequence limits and the priority order are the original's. Only CPU sequences exist: initialize and calculateRequiredMemorySize with compute sequences, and both compute dispatches, are not implemented, and createCompute and destroyCompute return the errors the original returns when no compute sequence was configured. The manager's state lives on the host heap, with only the block header written to the title's memory; the original keeps everything in that block, and a block smaller than 0x2d8 bytes throws here. The worker sleep policy, the spin count and the persistent thread count are validated and stored but change nothing, a factory priority above 1 throws, shutdown throws while a thread is blocked in a sequence wait, and using a sequence after its destroy throws. initialize returns 0 where the original returns the result of its last import (BG26hBGiNlw, not resolved to a name), the sceRazorCpuJobManager* profiler calls are not made, and a worker thread that cannot be created or configured throws where the original does not check. The order of the sequence and factory virtual functions is read from the modules' vtables only, since no title that calls them has been run
