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.

pm/kern: update for 14.0.0

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

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

* 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
