Cleanup: Fix build error with MSVC
Previously eigens internal include order somehow implicitly provided
M_PI and friends. The recent eigen version bump broke this implicit
behaviour, better to be explicit that we need the math defines for MSVC.

Fix T86591: Tracking backwards is slower
The root of the issue was caused by the PredictMarkerPosition()
always returning false when tracking backwards. This was making
it so tracker always had to run brute initialization, which is
an expensive operation.
From own timing here:
- Tracking forward takes 0.667637 seconds
- Tracking backward used to take 2.591856 seconds
- Tracking backward now takes 0.827724 seconds
This is a very nice speedup, although the tracking backwards is
still somewhat slower. Will be investigated further as part of
a regular development.

Fix T86262: Tracking backwards fails after gap in track
The issue was caused by a prediction algorithm detecting tracking the
wrong way. Solved by passing tracking direction explicitly, so that
prediction will always happen correctly regardless of the state of the
Tracks context.

Cleanup: clang-format
Is based on Google style which was used in the Libmv project before,
but is now consistently applied for the sources of the library itself
and to C-API. With some time C-API will likely be removed, and it
makes it easier to make it follow Libmv style, hence the diversion
from Blender's style.
There are quite some exceptions (clang-format off) in the code around
Eigen matrix initialization. It is rather annoying, and there could be
some neat way to make initialization readable without such exception.
Could be some places where loss of readability in matrix initialization
got lost as the change is quite big. If this has happened it is easier
to address readability once actually working on the code.
This change allowed to spot some missing header guards, so that's nice.
Doing it in bundled version, as the upstream library needs to have some
of the recent development ported over from bundle to upstream.
There should be no functional changes.

Simplify configuration of intrinsics to refine
Previously, only predefined and limited set of intrinsics combinations
could have been refined. This was caused by a bundle adjustment library
used in the early days of the solver.
Now it is possible to fully customize which intrinsics are to be refined
during camera solving. Internally solver supports per-parameter settings
but in the interface they are grouped as following:
* Focal length
* Optical center
* Radial distortion coefficients (which includes k1, k2, k3, k4)
* Tangential distortion coefficients (which includes p1, p2)

Fix wrong packing order of intrinsics for BA step
The order got broken when Brown distortion model has been added.
Made it so the indexing of parameters is strictly defined in the
parameter block, matching how parameters are used in the cost
function.
There is some duplication going on accessing parameters. This can
be refactored in the future, by either moving common parts packing
and cost function to an utility function in bundle.cc.
Alternatively, can introduce a public PackedIntrinsics class which
will contain a continuous block of parameters, and each of the
camera models will have API to be initialized from packed form and
to create this packed form.
The benefit of this approach over alternative solutions previously
made in the master branch or suggested in D9116 is that the specific
implementation of BA does not dictate the way how public classes need
to be organized. It is API which needs to define how implementation
goes, not the other way around.
Thanks Bastien and Ivan for the investigation!

Fix crash solving when having negative frames
Don't use linear array with frame as an index since it has the
following disadvantages:
- Requires every application to take care of frame remapping, which
could be way more annoying than it sounds.
- Inefficient from memory point of view when solving part of a footage
which is closer to the end of frame range.
Using map technically is slower from performance point of view, but
could not feel any difference as the actual computation is way more
complex than access of camera on individual frames.
