Merge branch 'hzhang/external-matfactor-options' into 'main'

Get options in symbolic factorization instead of MatGetFactor() using KSP/PC prefix when inside KSP

See merge request petsc/petsc!5230

Change matrix factor database options that occur in KSP/PC to always use KSP/PC options prefix

Add MatSetOptionsPrefixFactor() and MatAppendOptionsPrefixFactor() to allow controlling the options prefix
used by factors created from this matrix

Change MatSetOptionsPrefix() to no longer affect the options prefix used by factors created from this matrix

As part of the above work the handling of the factor matrix options is now done in code in the factor matrix
not in the code that originates the factor matrix

Update examples output to the new approach where the factored matrix prefix is set from the KSP/PC

Much of this work was performed by Hong Zhang
