Executable V8 pages include 3 reserved OS pages: one for the writable header and two as guards. On systems with 64k OS pages, the amount of allocatable space left for objects can then be quite smaller than the page size, only 64k for each 256k page. This means regular code objects cannot be larger than 64k, while the maximum regular object size is fixed to 128k, half of the page size. As a result code object never reach this limit and we can end up filling regular pages with few large code objects. To fix this, we change the maximum code object size to be runtime value, set to half of the allocatable space per page. On systems with 64k OS pages, the limit will be 32k. Alternatively, we could increase the V8 page size to 512k on Arm64 linux so we wouldn't waste code space. However, systems with 4k OS pages are more common, and those with 64k pages tend to have more memory available so we should be able to live with it.

allocation-builder.h was using methods defined in map-inl.h, which is not allowed. Thus move the respective methods to allocation-builder-inl.h.

Change the way that the (internal) await closures store the link to the generator object by introducing a dedicated AwaitContext, which stores the generator object into the extension slot (instead of misusing a regular FunctionContext here). Also unify the allocation+initialization of these contexts in the await-related builtins (both for async functions and generators). The rationale behind this is that for (zero-cost) async stack traces, we will need to dig into these contexts and we can do better checking with a dedicated instance type there. As an additional benefit, we save one word per await context, since we just use (the otherwise unused) extension slot to remember the generator object. As yet another benefit we will never accidentally use any of these contexts in the regular scope chain lookups, meaning we can also catch bugs there. And last but not least the objects printing machinery understands these contexts now and can even print the generator object for AwaitContexts for short printing, which is really valuable for debugging.

This is part of the effort to decrease the amount of undefined behavior. that v8 relies on. The main change here is to represent types with class Type rather than with pointer Type*. To make the CL smaller, I used an operator overload hack to separate the change from `->` to `.`. I am working on a CL that will remove the operator and change all those arrows to dots.

This makes all inline allocation constructions go through the existing {AllocationBuilder} helper class. It hence ensures there is a single place for all sanity checking and and makes use-sites easier to read.
