Put modifiers in the correct order

[bencomp]

What this PR does / why we need it:
This PR replaces final static with static final to comply with the Java Language Specification. It is a small step towards more consistent code.
While working in the affected files, I replaced a few calls to deprecated new Integer(String) and new Long(String) constructors with Integer.valueOf(String) and Long.valueOf(String) static method calls.

Which issue(s) this PR closes:

Closes #10074

Special notes for your reviewer:
Thank you for reviewing!

Suggestions on how to test this:
None. Perhaps in the future a Checkstyle run could fail if the order is incorrect.

Does this PR introduce a user interface change? If mockups are available, please link/include them here:
No.

Is there a release notes update needed for this change?:
No.

@bencomp Can you please add steps to test this ticket?

[bencomp]

This PR is basically about code style; no functionality changed and hence there's not really anything to test. Most importantly the code should compile as normal.

If you want an analysis of the changes, you could use the Sonar Maven goal and Sonarcloud to see that the warnings about modifier order (should) have gone away. @pdurbin and @poikilotherm have some experience with these steps.
