In the future, we will want to store hole search information in the
GlobalChi2Fitter's internal representation of a track state. This commit
adds the necessary data members as well as getters and setters to make
that possible.

There is really no reason for this getter method to not be const. The
returned pointer is to a const value, and the non-const qualification
makes it impossible to use this extremely useful getter in non-const
contexts.

Previously, this class had no getter to access the track states stored
within. That's a little bit weird, because it is something we access a
lot. This commit adds that getter.

For future changes, we will need to access header files defined in the
InDetReadoutGeometry to implement hole search. This commit adds the
dependency on that package to the CMake file of the TrkGlobalChi2Fitter.

This commit adds a configurable parameter to the TrkGlobalChi2Fitter
which enables it to do a hole search and export that information via a
track summary. It's disabled by default, and it doesn't actually do
anything yet. Actual hole search logic will be added later.

PanTau: set default p4 to TauEtaCalib (ATLTAU-1665)

See merge request !36733

Xiaozhong Huang authored 4 years ago and Adam Edward Barton committed 4 years ago

When PanTau fails, the p4 will at the default value, i.e. -1111. As
it has bad consequence when retrieving the p4, we now set the default
four momentum at TauEtaCalib.
