Touches some 'obvious' cases where histograms were misused.

- Replace copies by references to x, y and e histogram data
- Use setSharedX, setSharedY, setSharedE instead of manually copying the
values
- std::move vector data to histograms
- Fix off-by-one errors in SaveReflThreeColumnAsciiTest,
SaveReflCustomAsciiTest, SaveANSTOAsciiTest and ISISEnergyTransfer
- Fix issues in RefAxisTest

Re #24462

Also corrected indenting in CMakeList

Fixed error message

Added child algorithms to seeAlso of MuonPairingAsymmetry
Corrected truth table of checkConsistentPeriods
Moved alnum check to helper function
Updated error message to be more verbose
Added multi period example to docs

Child algorithms are added to seeAlso of MuonGroupingAsymmetry
is_alnum_method moved to MuonAlgorithmHelper
NormalizationIn added as property to MuonGroupingAsymmetry
calculateMuonAsymmetry renamed to estimateMuonAsymmetry
Docs updated for clarity
