refactor(core): store v8::Global<v8::Context> in an Rc (#18749)
Alternative to https://github.com/denoland/deno/pull/18726.

This was suggested by @piscisaureus. It's a bit ugly, but it does the
work and makes cloning `JsRealm` very cheap, while not requiring 
invasive changes.

Also managed to remove some vector and `v8::Global` clones which yields
about 5% improvement in the "async_ops_deferred.js" benchmark.

refactor(core): limit number of boundary crossings between Rust and V8 (#18652)
This commit refactors "deno_core" to do fewer boundary crossings
from Rust to V8. In other words we are now calling V8 from Rust fewer
times.

This is done by merging 3 distinct callbacks into a single one. Instead
of having "op resolve" callback, "next tick" callback and "macrotask
queue" callback, we now have only "Deno.core.eventLoopTick" callback,
which is responsible for doing the same actions previous 3 callbacks.

On each of the event loop we were doing at least 2 boundary crosses
(timers macrotask queue callback and unhandled promise rejection
callback) and up to 4 crosses if there were op response and next tick
callbacks coming from Node.js compatibility layer. Now this is all done
in a single callback.

Closes https://github.com/denoland/deno/issues/18620

This will help make reviews easier for #15760, which moves a number of
methods related to module loading from `JsRuntime` into `JsRealm`.
