If a call to a builtin is generated at run-time (vs at snapshot time)
we don't need to tag the call/jump with relocation info, as the builtin
address will not change.
The only way to generate a builtin call at snapshot time is via
MacroAssembler::JumpToInstructionStream where we keep OFF_HEAP_TARGET.
The reloc info for builtin calls and jumps is set to NONE.

Requires plumbing Isolate* through several Parser functions which
previously avoided it because of worries about accessing the heap off
the main thread. In all off-main-thread cases, isolate will be nullptr

Also deletes unused function ParseInfo::ReopenHandlesInNewHandleScope.

Currently each isolate stores its own array of
{CallInterfaceDescriptorData}. This array has size 173, and each entry
has 40 bytes. That's already 7kB per isolate.
Additionally, each {CallInterfaceDescriptorData} allocates two
heap-allocated arrays, which probably add up to more than the static
size of the {CallInterfaceDescriptorData}. Note that all the
{CallInterfaceDescriptorData} instances are initialized eagerly on
isolate creation.
Since {CallInterfaceDescriptor} is totally isolate independent itself,
this CL refactors the current design to avoid a copy of them per
isolate, and instead shares them process-wide. Still, we need to free
the allocated heap arrays when the last isolate dies to avoid leaks.
This can probably be refactored later by statically initializing more
and avoiding the heap allocations all together.
This refactoring will also allow us to use {CallInterfaceDescriptor}s
from wasm background compilation threads, which are not bound to any
isolate.

I plan to move the {Managed<NativeModule>} from {WasmCompiledModule} to

{WasmModuleObject} *before* compilation, so that the {CompilationState}

This CL prepares that refactoring by storing the {WasmModule} in a

We currently have a system where the protected instructions are
unregistered when the last instance dies, and registered again on the
next instantiation. This is triggered by {WasmCompiledModule::Reset}.
Since the reference to the {NativeModule} will move to the
{WasmModuleObject}, and this object stays alive even if the last
instance dies, this will become hard to maintain.
It will also make it harder to share wasm code across isolates.
This CL refactors this to register trap handler data once when the code
is added to the {NativeModule}, and releases it if the code dies.

This is a step towards avoiding materializing function_ altogether if we deoptimize. Typically we only need the SharedFunctionInfo.

It only has one call size ({CompileToModuleObject}), which just tail
calls into {CompileToModuleObjectInternal}. Thus, merge the two.
