DebugOnly makes binding to other languages (e.g. Rust) more complicated than needed.

js::Class op are often all null. And when they're not all null, they're often
duplicated among classes. By pulling them out into their own struct, and using a
(possibly null) pointer in js::Class, we can save 114 KiB per process on
64-bit, and half that on 32-bit.

|oOps| is short for "objectOps", which will contrast with the |cOps| "classOps"
field that the next patch will introduce.

js::ClassExtension is often all null. When it's not all null, it's often
duplicated among classes. By pulling it out into its own struct, and using a
(possibly null) pointer in js::Class, we can save 17 KiB per process on
64-bit, and half that on 32-bit.

Exceptions:
- AutoSetNewObjectMetadata and its related type are still exclusively about objects.
- JSCompartment::objectMetadataTable is still only about objects.
- the ObjectMetadataMap type still only has objects as keys.
Non-exceptions:
The builder type, and the JSCompartment member:
ObjectMetadataCallback -> AllocationMetadataBuilder
objectMetadataCallback -> allocationMetadataBuilder
jsfriendapi.h interface:
SetObjectMetadataCallback -> SetAllocationMetadataBuilder
GetObjectMetadata -> GetAllocationMetadata
JSCompartment methods:
hasObjectMetadataCallback -> hasAllocationMetadataBuilder
getObjectMetadataCallback -> getAllocationMetadataBuilder
setObjectMetadataCallback -> setAllocationMetadataBuilder
forgetObjectMetadataCallback -> forgetAllocationMetadataBuilder
addressOfMetadataCallback -> addressOfMetadataBuilder
Shell and testing functions:
SavedStacksMetadataCallback -> SavedStacksMetadataBuilder
ShellObjectMetadataCallback -> ShellAllocationMetadataBuilder
EnableShellObjectMetadataCallback -> EnableShellAllocationMetadataBuilder
enableShellObjectMetadataCallback -> enableShellAllocationMetadataBuilder
GetObjectMetadata -> GetAllocationMetadata
getObjectMetadata -> getAllocationMetadata
Delayed metadata collection:

js::ClassSpec is often all null. When it's not all null, it's often duplicated
among classes. By pulling it out into its own struct, and using a (possibly
null) pointer in js::Class, we can save 138 KiB per process on 64-bit, and half
that on 32-bit.

js::ObjectOps is often all null. When it's not all null, it's often duplicated
many times among classes. By pulling it out into its own struct, and using a
(possibly null) pointer in js::Class, we can save 208 KiB per process on
64-bit, and half that on 32-bit.
