Since it fits nicely, this CL as a bonus includes the planned change to
make Handle::location() return an Address*, in the process dropping the
temporarily needed duplicate Handle::location_as_address_ptr().

Instead, create it when needed and pass it down to the actual
compilation.
This saves memory by making the WasmCompilationUnit smaller and will
eventually allow us to implement the trap handler fallback correctly by
using an updated ModuleEnv in background compilation and tier up.

The WasmMemoryTracker keeps track of reserved memory in order to avoid
running out of virtual address space. So far, we were only tracking
reservations for wasm memory, and not for code. This CL changes that to
also include code reservations.
