TraceProcesor: unique_ptr<uint8_t> -> TraceBlob A non-functional refactoring to TraceProcessor. This CL mainly replaces all the places where we pass around a pair of (unique_ptr<uint8_t>, size_t) with an explicit TraceBlob. It also simplifies a bit the TraceBlobView code, reducing the indirection layers required to handle refcounting (the overall refcounting principle still holds though). The main benefit of that is removing one layer of pointer chasing when accessing TraceBlobView.data(). The main reason of this CL is to introduce support for mmaping the trace file on desktop (but still retain the owned-buf semantic for wasm and platforms where mmap is not supported).
