ZScript DAP Debug server (#3009)
* Add STL-standard type traits and functions to TMap to enable for loop iteration

* add third-party range-map library

I have e-mailed the author for clarifcation on the license, will update this when they respond

* vcpkg: Add cppdap and eventpp libraries, update baseline

* DAP implementation

* Add `FileSystem::FileHash()` to get the CRC32 hash

* add `starting_offset` param to `VMDisasm()` for debugger disassembly view

Defaults to `0`, should not change output if it's not set

* Add `VMFrameStack::HasFrames()` to prevent assertions when inspecting in the debugger

* Add `PC` field to VMFrame, ensure that it is updated whenever vm increments/decrements the pc

Does not change alignment, the offsets used in VMFrame still work
We need this for the debugger because we otherwise have no way to get the pc; it was a local in `ExecScriptFunc()`

* `ZCCCompiler::CreateClassTypes()`: ensure SourceLumpName is set for classes derived from non-native classes

* start debug server in d_main, add `vm_debug` cvars and `-debug` CLI arg

* Add documentation for `vm_debug` cvars

* vm_exec: Add debugger hooks for instruction execution events

* c_console: Add debugger hooks for logging events in `PrintString`

* add `.cache/` to gitignore

* vendor cppdap on main @ 6464cd7

Patches:
removed .gitmodules (submodules were thirdparty/json, thirdparty/googletest)
removed thirdparty/googletest, not needed
removed thirdparty/json/docs, thirdparty/json/test, thirdparty/json/benchmarks to prevent massive bloat

* vendor eventpp on master @ 1224dd6

* build: use internal cppdap and eventpp by default

* dap: fix Binary::GetFunctionLineRange()

* fix bug in range_map::find_ranges

* make Binary dap::Source dynamic

* cache source code upon retrieval

* refactor Binary into a class, cleanup PexCache

* fix ending session gracefully

* d_main: Stop debug server in D_Cleanup()

* Fix connecting to debugger when session already started

* cleanup unused stuff in ZScriptDebugger

* always send TerminateEvents on disconnect if initialized

* tweak color display

* Don't cache disassembly lines when scanning scripts

* Cache nodes when getting runtime state

* WIP display locals

* Fix display of static arrays

* Ensure names display in proper order

* dap: Fix struct locals display, add args display

* Support `start` parameter

* Support `filter` parameter

* remove struct unbound native data display

Practically useless for debugging zscript and didn't work properly anyway

* d_main: fix vm_jit and vm_jit not being disabled soon enough

* support breaking on abort exceptions

* dap: refactor game event emitter functions into seperate header

* dap: show native functions on stack

* dap: Remove "Native" from exception handling, simplify exception event emit

* dap: add instruction breakpoints

* dap: fix display of locals not in scope yet

* dap: Make disassembly view display invalid instructions for non-code addresses

* dap: remove dot initializers

* dap: fix local structs in scope

* dap: don't parse the non-used options in the launch/attach requests

* dap: fix local struct view

* dap: Fix displaying objects that aren't their actual types

* dap: Fix action and state handling

* dap: stack display view

* dap: fix object display view

* d_dehacked: set qualified name in addition to the printable name

* dap: fix displaying breakpoint errors when script isn't loaded

* dap: remove debug print

* dap: Display parameter names

* dap: Turn down verbosity of logging

* dap: fix disassembly view

* dap: fix performance problems with arrays

* c_console: emit event only if not PRINT_NODAPEVENT

* dap: improve logging

* dap: update upstream cppdap library to fix deadlocks on no bind

* dap: Fix ending session on client socket closed

* dap: prevent DebugServer.h from pulling in `dap` and `ZScriptDebugger.h`

* dap: fix pause event not being emitted on pause

* dap: remove eventpp emitters, way too slow

* Remove eventpp dependency

* dap: Display correct register names

* dap: Show special inits in registers

* dap: Add stack offset to VMLocalVariable

* dap: fix display of static arrays and local variables on stack vs. registers

* dap: fix displaying function pointers

* dap: tweak color display

* dap: fix scalar display < 4

* dap: add Globals display to debugger

* dap: unify methods to get vmvalue

* dap: rename free method to freeValue to avoid running afoul of macro defs

* fix windows builds

* fix compile on linux

* cleanup

* Fix display of function breakpoints

* dap: Don't send back binary files

* dap: include sbarinfo in script types (no debug support for anything but zscript yet, this is just for returning source info)

* dap: don't show ending session message unless initialized

* fix erroneous commit

* dap: handle evaluate requests

* Fix getting bitfield values

* Add CVars Scope and evaluation

* add running console commands from repl

* dap: disable commands via repl for now

* fix loading functions DECORATE scripts

* Add source information to Dehacked VM functions, add debugging support

* dap: cleanup

* fix resolving archive paths

* don't send source back on native stack frames

* handle `modules` request

* cleanup

* allow evaluating cvars on hover

* fix oob bpinfos

* fix restarting the game blowing out the debug server

* dap: process input events while paused to prevent deadlocks

* fix getting local state

* dap: fix LocalState alignment

* dap: fix DumpStateHelper

* update cppdap protocol version to 1.68.0

* remove cppdap from vcpkg deps

We can't use the upstream version anyway because the maintainers are not merging our patches

* dap: make named variable nodes derive from the same class

* dap: make cvar scope available in native stack frames

* handle local variables with conflicting names

* add I_GetWindowEvent() to win32 to only process window events when debugging is paused

* dap: fix evaluate

* dap: fix display of `out` variables
