Adding an accessor for groomed jet mass in 10.0.x

[arizzi]

The JME recommendations for groomed masses changed since we implemented miniaod, so this adds some accessors to take the invariant mass of all groomed subjets, which gives the groomed jet mass.

This is also planned to be implemented in nanoaod. @rappoccio @gpetruc

Same as:
#21901 #21902

backport of #21902

[slava77]

for #21944 0e39d13

• new pat::Jet::groomedMass accessors, needed for analysis
• the same topic branch as the 10_1_X/master version in Adding an accessor for groomed jet mass in 10.x #21902
• jenkins tests pass

[arizzi]

@fabiocos if we want 10.0.X to become the analysis release (e.g. support NANOAOD) this version of the additional pat::Jet accessors PR should be merged too.
