lift wait-for-process-memory-cache-update out of d_process_write, since that path runs on control thread now too as the general 'process handle write' abstraction - just move into the rd_eval_space_write path, since that wait was only for UI benefit anyways

dbg_engine: shift thread register reads / process memory reads -> abstraction layer, rather than directly calling into demon; cache crash dump info, like thread info & memory ranges; implement thread reg reads & memory reads for dumps by using this acceleration structure when we have a dump handle, instead of regular demon reads.

minidump format types; open crash dump command, stub out opening path in control thread; expand d_handles to support machine id, entity id, *and* 'controller kind', which can be either a dump file or a demon - this properly separates the true process control abstraction (demon) from opening a regular dump file on any machine, which will let us trivially support any kind of dump file on any platform; also fix bad cfg tree state leak

artifact_cache: fix leak of old-generation artifacts, when those artifacts are replaced by newer generation computations. artifacts can opaquely hold things like arena pointers, and so when we replace them in the cache, we need to respect the lookup api's provision of create/destroy hooks for the cache, such that the artifacts can be released correctly (using the destroy hook) before being replaced. this is separate from regular eviction.

add support for CFA in the eval system
...
Canonical Frame Address is a DWARF-only concept encoded in the unwind info.
Debugger must store this data for each call frame and provide it to
the eval system based on selected stack frame.
To abstract over format details, we introduce a "Frame Unwind Context".
For DWARF, this context maintains the intermediate unwind state and exposes
the CFA, whereas for PE, it remains empty.

WIP add support for GNU LibC TLS model
...
Unlike on Windows, TLS index isn't part of the module format. glibc stores
it in the opaque link_map struct. There are many different heuristics
a debugger can use to locate it but most of them are unreliable and
prone to errors, or don't work when debugger attaches to a process.
We adopt the newer approach of looking for special symbols
in glibc that provide TLS index offset. These symbols were added in
2021, so programs linked with older glibc won't have TLS support.
