fix(core): make errors more resistant to tampering (#15789)
This commit makes error objects more resistant to
prototype tampering.

This bug was found when updating the deno_std Node compatibility
layer to Node 18. The Node test 'parallel/test-assert-fail.js'
was breaking std's assertion library.

perf(ops): Monomorphic sync op calls (#15337)
Welcome to better optimised op calls! Currently opSync is called with parameters of every type and count. This most definitely makes the call megamorphic. Additionally, it seems that spread params leads to V8 not being able to optimise the calls quite as well (apparently Fast Calls cannot be used with spread params).

Monomorphising op calls should lead to some improved performance. Now that unwrapping of sync ops results is done on Rust side, this is pretty simple:

```
opSync("op_foo", param1, param2);
// -> turns to
ops.op_foo(param1, param2);
```

This means sync op calls are now just directly calling the native binding function. When V8 Fast API Calls are enabled, this will enable those to be called on the optimised path.

Monomorphising async ops likely requires using callbacks and is left as an exercise to the reader.

refactor: add core.formatLocationFilename, remove op_format_filename (#14474)
This commit moves "op_format_location" to "core/ops_builtin.rs"
and removes "Deno.core.createPrepareStackTrace" in favor of
"Deno.core.prepareStackTrace".

refactor: Move source map lookups to core (#14274)
The following transformations gradually faced by "JsError" have all been 
moved up front to "JsError::from_v8_exception()": 

- finding the first non-"deno:" source line; 
- moving "JsError::script_resource_name" etc. into the first error stack 
in case of syntax errors; 
- source mapping "JsError::script_resource_name" etc. when wrapping 
the error even though the frame locations are source mapped earlier; 
- removing "JsError::{script_resource_name,line_number,start_column,end_column}"
entirely in favour of "js_error.frames.get(0)". 

We also no longer pass a js-side callback to "core/02_error.js" from cli. 
I avoided doing this on previous occasions because the source map lookups 
were in an awkward place.

refactor: introduce primordials (#10939)
This commit introduces primordials to deno_core. Primordials are a
frozen set of all intrinsic objects in the runtime. They are not
vulnerable to prototype pollution.
