Break up headers into constituent parts This is part of a broader change to make header files better represent the dependencies between one another (see https://github.com/jemalloc/jemalloc/issues/533). It breaks up component headers into smaller parts that can be made to have a simpler dependency graph. For the autogenerated headers (smoothstep.h and size_classes.h), no splitting was necessary, so I didn't add support to emit multiple headers.

Prof: Add prof_unbias. This gives more accurate attribution of bytes and counts to stack traces, without introducing backwards incompatibilities in heap-profile parsing tools. We track the ideal reported (to the end user) number of bytes more carefully inside core jemalloc. When dumping heap profiles, insteading of outputting our counts directly, we output counts that will cause parsing tools to give a result close to the value we want. We retain the old version as an opt setting, to let users who are tracking values on a per-component basis to keep their metrics stable until they decide to switch.

Restructure profiling Develop new data structure and code logic for holding profiling related information stored in the extent that may be needed after the extent is released, which in particular is the case for the reallocation code path (e.g. in `rallocx()` and `xallocx()`). The data structure is a generalization of `prof_tctx_t`: we previously only copy out the `prof_tctx` before the extent is released, but we may be in need of additional fields. Currently the only additional field is the allocation time field, but there may be more fields in the future. The restructuring also resolved a bug: `prof_realloc()` mistakenly passed the new `ptr` to `prof_free_sampled_object()`, but passing in the `old_ptr` would crash because it's already been released. Now the essential profiling information is collectively copied out early and safely passed to `prof_free_sampled_object()` after the extent is released.
