fs.mitm: add and use memlet module to temporarily steal applet memory while building romfs images. ...

Starting in 20.0.0, the browser needs more applet memory to function, so we can't steal as much any more.
Thus, we now steal 14 MB on 20.0.0+ instead of 40MB.

However, since this reduces memory available for custom system modules, we are adjusting to compensate.
ams.mitm's heap size has been reduced from 32MB to 12MB (recovering 20MB).
In addition, fs.mitm now uses a new mechanism for stealing memory from the applet pool while romfs is being built.

On net, we are compromising:
    * Custom sysmodules lose memory available to them.
        On 19.0.0/AMS 1.8.0, there was 30 MB available for custom sysmodules.
        Stealing 14 MB instead of 40 MB, we lose 26 MB of that. Reducing ams.mitm's usage will gain us back 20.
        Nintendo also appears to...use 4 extra MB, in 20.0.0, from my test homebrew.
        So on 20.0.0/AMS 1.9.0, there should be 20 MB available for custom sysmodules.
        On the bright side, on <20.0.0/AMS 1.9.0, I guess there will be 50 MB available for custom sysmodules now?
    * totk mods will lose the ability to...put every file in the romfs on sd card. There will be some unknown maximum filecount for totk mods.
        On the bright side, implementing the transient memory stealing should improve compatibility for some mods which strictly add files?

ldr/pm: update for 20.0.0 abi changes

pm: add new 19.0.0 commands ...

This is functionally correct, but I have no idea what these are meant to represent.
These functions are completely unused on NX.

kern/strat: update for new DebugFlags capability semantics

pm: improve resource limit management accuracy ...

This change was made for #2255, but the issue creator never confirmed if it resolved the issue.

This *does* better reflect what Nintendo's pm does, though, so I'm going to commit it regardless.

pm: update to reflect 17.0.0 internal design changes

pm: since 15.0.0, WaitApplicationMemoryAvailable is more lenient

pm: adjust resource limit function names

romfs/ams.mitm/pm: refactor to dynamically steal heap for certain games. (#2122) ...

* fs.mitm: skeleton the use of special allocation in romfs build

* pm: add api for ams.mitm to steal application memory

* pm/mitm: okay, that api won't work, try a different one

* romfs: revert memory usage increases; we'll handle torture games case-by-case.

* pm/romfs: first (broken?) pass at dynamic heap.

I cannot wait to figure out all the ways this is wrong.

* Release the dynamic heap a little more eagerly

* romfs: animal crossing is also not a nice game

* romfs: fix issues in close-during-build

* romfs: zelda is a blight upon this earth

kern/pm: only steal 8 MB from applet. ...

WebApplet crashes on exit with 16 more MB stolen, apparently.

romfs: thank you fire emblem, very cool (closes #2021)

pm: grant access to GetResourceLimitPeakValue

pm/kern: update for 14.0.0

ams: support building unit test programs on windows/linux/macos

Integrate new result macros. (#1780) ...

* result: try out some experimental shenanigans

* result: sketch out some more shenanigans

* result: see what it looks like to convert kernel to use result conds instead of guards

* make rest of kernel use experimental new macro-ing

sm/tipc: minor cleanup

ams: allow bootloader to merely approximate correct target firmware

strat: use m_ for member variables

ams: replace most remaining operator & with std::addressof

strat: refactor address taking of form &var[...]

strat: use ams::Main() instead of main(argc, argv)

strat: build sysmodules with -Wextra/-Werror

strat: use sf::NativeHandle for ipc templating

strat: prefer os::NativeHandle to Handle/svc::Handle where sensible

strat: use svc:: over ::svc

ams: the copyright^H^H^H^H^H^H^Hmplex plane is the algebraic closure of the reals

pm/cfg: simplify initial process id range logic

strat: automatic program id detection
