The patch makes the following proxy changes:
* The number of slots in ProxyValueArray is now dynamic and depends on the number of reserved slots we get from the Class.
* "Extra slots" was renamed to "Reserved slots" to make this clearer.
* All proxy Classes now have 2 reserved slots, but it should be easy to change that for proxy Classes that need more than 2 slots.
* Proxies now store a pointer to these slots and this means GetReservedSlot and SetReservedSlot can be used on proxies as well. We no longer need GetReservedOrProxyPrivateSlot and SetReservedOrProxyPrivateSlot.
And some changes to make DOM Proxies work with this:
* We now store the C++ object in the first reserved slot (DOM_OBJECT_SLOT) instead of in the proxy's private slot. This is pretty nice because it matches what we do for non-proxy DOM objects.
* We now store the expando in the proxy's private slot so I removed GetDOMProxyExpandoSlot and changed the IC code to get the expando from the private slot instead.
AddPseudoEntry() has a single callsite which always passes nullptr for the
last argument. This means that js::ProfilingGetPC() is never called, and so can
be removed. (Even if it was called, it always returns nullptr because ipToPC()
always returns nullptr!)

Remove the definition of sig_safe_t, which is only used by PseudoStack,
and replace the uses with mozilla::Atomic<uint32_t>.

They were previously using duplicate definitions and this DRYs them up. This is
needed because bindgen can't understand `mozilla::Conditional`, and so we want
to replace `MaybeWrapped` with something a little simpler when doing bindings
generation, and its easier if we don't have to repeat our desired replacement as
well.
Zero-sized base classes are a particular pain point for bindgen. When used as a
base class they can be truly zero sized, but when used directly they have to
have a byte inserted to enable C++'s distinct-objects-have-distinct-addresses
rule. Bindgen could generate two different struct definitions for such cases,
but then users need to know which to use at which time and its simpler to just
avoid zero sized base classes.
Instead of copying and concatenating strings into an mDest buffer in
SamplerStackFramePrintfRAII, require callers to keep the string buffer alive
for the duration of the current scope, and store the pointer to the annotation
string in the ProfileEntry. During stackwalking, concatenate the label and the
annotation (separated by a space) and store the resulting string in the
profile buffer.
