content: Use the memory-infra graph API for GpuMemoryBufferManager.

This makes BrowserGpuMemoryBufferManager emit dumps of the form:
gpumemorybuffer/client_X/buffer_Y

This allows child process GpuMemoryBuffer clients to create a dump
for the same buffer by attaching the same guid to it. By doing that,
the trace-viewer UI can infer that the two buffers, that are,
"gpumemorybuffer/client_X/buffer_Y" on the browser side and
"gpumemorybuffer/buffer_Y" on the child side, refer to the same
memory and should be counted only once.
