Resolved Export.cpp and GuestVrTracker2.cpp keeping main's header layout; the new sceHmd2Internal exports are declared in the libSceHmd2 header and the test uses the library headers.

sceVrTracker2Initialize follows the order read from firmware 13.60
libSceVrTracker2.sprx (disassembly, not measured on a console). It
rejects with 0x8A740006, in order: a null record or a size other than
72; a mode other than 0, 1000 or 1001; a null work memory; a size below
the mode's 32 MiB, 7 MiB or 3 MiB; an alignment below 0x10000; a
non-zero reserved byte at 0x3a..0x47; a thread priority outside
256..767; an affinity mask outside bits 0..12 in mode 0 or outside
0xEA00 in modes 1000 and 1001. It then moves the module state from 0 to
1 and returns 0x8A740002 if it was not 0.
From there every failure undoes what the call opened and resets the
state to 0. Mode 0 clears the first 32 MiB of work memory first. The
application attribute checks on the sceKernelGetAppInfo2 record
(0x8A74001E, 0x8A740020) are skipped: the host has none, and a zeroed
record passes them. The signed option at 0x39 accepts -1 and 0,
and 1 only for titles compiled with SDK 7.00 or later. Modes 0 and 1000
then call libSceHmd2 TrackingOpen, TrackingStart, LedDetectorOpen and
LedDetectorStart and return the first non-zero result unchanged.
Without a headset main's libSceHmd2 answers 0 and -1 (its measured
pre-initialization answers), so Initialize returns -1 and every other
export keeps answering 0x8A740001.
Modes 1000 and 1001 need the application category, which the host does
not have, and a fully successful Hmd2 sequence would need the tracker
runtime; both throw. The eight tracking and LED-detector exports become
named functions in libSceHmd2 so that libSceVrTracker2 can import them
by name; their answers are unchanged.

PPSA09030's Media/Plugins/psvr2.prx imports sceHmd2ReprojectionGetStatus
from libSceHmd2 and sceVrTracker2GetCoordinateSystem and
sceVrTracker2GetPlayAreaBoundaryGeometry from libSceVrTracker2, so the
title does not start with the plugin loaded (discussion #4680). Declare
the three as throwing exports, like the earlier PS VR2 imports of
PPSA29866. The names resolve from the NIDs 8GkaY2B7opM, Y-3JCiU9bbU
and SCph4ZbkqzU with tools/nid_names.py; no reference gives their
signatures.

PPSA07411 (Resident Evil 4) fails to load without these imports. Their signatures are unknown, so they are declared without parameters and throw until they are implemented. Adds a TechnicalDebt entry.

Propagation: Paradise Hotel (PPSA15878) does not load on main: its
executable imports 15 PS VR2 functions that no library exports, the
first reported being sceVrTracker2GetPlayAreaOrientedBoundingBox
(snYs7Nf-RKk). Declare the nine libSceHmd2 reprojection and gaze
exports, three libSceVrTracker2 exports and three scePadVrController
trigger effect exports, without parameters, as throwing stubs. Names
come from the aerolib NID list.
