libstratosphere: use from /atmosphere/libraries

Improve exception wrapping

dmnt_cheat_vm: Correct register Restore and ClearRegs behavior ...

Previously they were performing the same behavior as the Save and
ClearSave opcode types.

ams_mitm: Implement emummc Nintendo folder redirection

compat fixes for libnx master

ams_mitm: Implement system settings mitm

mitm/cfg: pass around override status for decision-making

strat: TitleId -> ProgramId, titles->contents

strat: split out common functionality for future meso use

namespace sts -> namespace ams ...

namespace sts::ams -> ams::exosphere, ams::.

This is to facilitate future use of ams:: namespace code in
mesosphere, as we'll want to include ams::util, ams::result, ams::svc...

Results: Implement namespaced, type-safe results. ...

Because I was working on multiple things at once, this commit also:
- Adds wrappers for/linker flags to wrap CXX exceptions to make them
  abort. This saves ~0x8000 of memory in every system module.
- Broadly replaces lines of the pattern if (cond) { return ResultX; }
  with R_UNLESS(!cond, ResultX());.
- Reworks the R_TRY_CATCH macros (and the result macros in general).

libstrat: fix domain issues. in/out objects now work.

libstrat: namespace remaining non-namespaced code. more new-ipc updates

strat: statically allocate additional threads

strat: update for latest libnx commit

dmnt: update for new-ipc

os: implement waitable management. ...

This implements waitable management for Events (and
implements Events). It also refactors PM to use new
Event/Waitable semantics, and also adds STS_ASSERT
as a macro for asserting a boolean expression. The
rest of stratosphere has been refactored to use
STS_ASSERT whenever possible.
