This adds a planner event to request V8 heap statistics.
This data is gathered from the JS side because the related methods from the rust side require a
&mutaccess to the runtime, which is impossible since it already runs in an infinite loop.Since we elected to not run the prelude parts of deno which register functions like
Deno.memory_usage, we intern the op_runtime_memory_usage function and import it directly as a host function, as we've done already withop_crypto_get_random_values. To avoid hosting too much code, therssfield is not filled (it needs platform specific functions), since that info can generally be obtained by other means.
