feat(core): add crashtracker, update libdatadog to v10.0

[sanchda]

PROF-10246

This PR does two things

First, it updates the libdatadog dependency to v10.0. This enhances the RSS overhead of profiling collection, among many other fixups.

Second, it exposes an interface to the crashtracker, which is a component shipped out of the libdatadog profiling FFI. The precise build process for crashtracker here is somewhat convoluted because:

• We want to make the final distribution size as small as possible
• In service of that point, libdatadog and the associated shim wrappers are consolidated into a single libdd_wrapper.so
• On Linux, that .so is configured in the RPATH of many other .so
• Moreover, crashtracker requires a receiver binary, which again must rely on libdd_wrapper.so
• The interface to crashtracker is cythonized (for now), forcing us to transpile, then compile and link manually instead of through the normal cythonize() helpers (i.e., we build in cmake instead of the usual cythonize in setup.py)
