Changes:
- Rename ObjectReferenceKnowledgs::object_must_be_data_ref to
reference_kind, introduce an enum to describe it.
- In both compilers, remove the dynamic check whether the object is an
array/struct. This is known statically. Instead, if we are checking
for a function, just check for rtt equality and exit.
- Remove is_data_ref_type(), replace it in the compilers with calls to
has_signature().
- Restructure AllocateSubRtt() to handle function rtts properly.
- Add a couple execution tests.

The icache and jump-table-assembler tests need memory that is both
writable and executable. On Mac, to do this we need to pass MAP_JIT to
mmap which is wired with the VirtualMemory::JitPermission flag.

This prototypes i32x4.widen_i8x16_s and i32x4.widen_i8x16_u for the
interpreter.
This is the first instruction of its kind, a post-mvp, unary operation
that takes one immediate. Which is why there are more changes to the
decoder than usual.

For asynchronous compilation, the beginning and end of compilation are
marked with different trace events. To allow to connect these events, a
compilation id is added to the start and end events. Note that the
compilation id is not added to all trace events to avoid bloating
traces. Ids may be added later to these events if necessary.

For memory64, the init expressions for data segments provide a 64-bit
value. This CL adds a new {EvalUint64InitExpr} function alongside
{EvalUint32InitExpr}. It supports i64.const and global.get operations.

`0x12345678` will be written to memory in the same order on BE
machines however, as Wasm is LE enforced, a memory load will
force a byte reverse operation on BE machines which changes the value.
To fix the problem, we write the reversed value to memory.
