[Core] Add GeometryMetricsTensorAdaptor

[sunethwarna]

📝 Description
This PR adds GeometryMetricsTensorAdaptor which is able to compute DomainSize of each geometry in the given Geometries, Elements or Conditions container.

Thsi is made such that, it would be easier to extend if someone needs Length, Area, Volume, etc methods in future as well.

🆕 Changelog

• Adds GeometryMetricsTensorAdaptor
• Adds unit tests

Just to comment that DomainSize is alrrady exppsed in the geoemtriestensoradaptor

Hmm... Is it? I checked, it exposes the Jacobians, but not the domain size straight away. Unless I do the jacobians determinant integration manually, I don't see a way to get the domain size. Am I missing something @RiccardoRossi ?

i thought it was one of the ones exposed...yet if it is not it is a trivial change to add it ...

@RiccardoRossi We could change the GeometriesTensorAdaptor to have the GP based domain size calculation. But, this will not be exactly the same as the method (or the value) which is used in Geometry::DomainSize method for some geometries. For sensitivity analysis, it is important to be consistent with the forward analysis DomainSize and the adjoint analysis / sensitivity post processing DomainSize computation. Therefore, I would keep this, and could extend the GeometriesTensorAdaptor to support DomainSize, if the need arise. [We have analytical domain size sensitivity computation already implemented for most of the geometries]

Another thing is, all the computations in GeometriesTensorAdaptor currently requires a variable and ProcessInfo. If we put this there, then they should be optional [Not a big issue, but just a small caveat]
