[nce] add split patch mode to support modules bigger than 128MB (#3489)
nce patcher was extended to support modules larger than 128MB due to ARM64 branch limit. now added a pre-patch and (existing) post-patch module code. Allowwing MRS/MSR/SVC handler to remain within branch branch range

[common, core] remove uneeded memory indirection overhead at startup (#3306)
for core stuff:
just remove unique ptrs that dont need any pointer stability at all (afterall its an allocation within an allocation so yeah)

for fibers:
Main reasoning behind this is because virtualBuffer<> is stupidly fucking expensive and it also clutters my fstat view
ALSO mmap is a syscall, syscalls are bad for performance or whatever
ALSO std::vector<> is better suited for handling this kind of "fixed size thing where its like big but not THAT big" (512 KiB isn't going to kill your memory usage for each fiber...)

for core.cpp stuff
- inlines stuff into std::optional<> as opposed to std::unique_ptr<> (because yknow, we are making the Impl from an unique_ptr, allocating within an allocation is unnecessary)
- reorganizes the structures a bit so padding doesnt screw us up (it's not perfect but eh saves a measly 44 bytes)
- removes unused/dead code
- uses std::vector<> instead of std::deque<>

no perf impact expected, maybe some initialisation boost but very minimal impact nonethless
lto gets rid of most calls anyways - the heavy issue is with shared_ptr and the cache coherency from the atomics... but i clumped them together because well, they kinda do not suffer from cache coherency - hopefully not a mistake

this balloons the size of Impl to about 1.67 MB - which is fine because we throw it in the stack anyways

REST OF INTERFACES: most of them ballooned in size as well, but overhead is ok since its an allocation within an alloc, no stack is used (when it comes to storing these i mean)

[core/loader] Implement a bit improper ASLR (#2945)
A bit improper of an ASLR - it does something but something good? Who knows...
All I know is that there is a non-uniform distrobution for rand() and that rng_seed is likely a better solution?
I don't know

[kernel] Implement code address offset for Skyline compatibility (#2858)
- Add debug logging for 32-bit syscall argument tracking.

- Add CodeStartOffset constant (0x500000) applied to only 32-bit code address space
  types in KProcess::LoadFromMetadata.

- Replace CheckMemoryStateContiguous with two-stage CheckMemoryState
  in KPageTableBase::UnmapCodeMemory to discover and verify memory
  state more accurately.

Based on similar fixes in Ryujinx (commit 5e9678c8fe)
Fixes compatibility with:
- Skyline 32-bit modding framework
- CTGP-DX (Mario Kart 8 Deluxe mod)
- Other homebrew using 32bit Skyline

Kyle Kienapfel d886438754 Add break for default cases
Visual Studio has an option to search all files in a solution, so I
did a search in there for "default:" looking for any missing break
statements.

I've left out default statements that return something, and that throw
something, even if via ThrowInvalidType. UNREACHABLE leads towards throw

R_THROW macro leads towards a return
