bf80f6c7 - [Static Runtime] prim::fork asyunchronous execution on JIT interpreter (#78858)

[Static Runtime] prim::fork asyunchronous execution on JIT interpreter (#78858) Summary: prim::fork was executed synchronously in the main thread - Added changes that executes the prim::fork calls on asynchronously on one of the threads from TaskThreadPoolBase defined in aten - Changes are tested via pytorch profiler tracing. Fork calls are executed on different threads Test Plan: local tests scripts exected: - buck run mode/opt caffe2/test:static_runtime - buck run caffe2/benchmarks/static_runtime/fb:test_fb_operators - buck run caffe2/benchmarks/static_runtime:static_runtime_cpptest Executing pytorch profiler to see the spawned execution of fork operations in parallel on different threads Differential Revision: D36909308 Pull Request resolved: https://github.com/pytorch/pytorch/pull/78858 Approved by: https://github.com/mikeiovine
