[FLINK-39928][ci] If there are changes in tests only then skip non related CI jobs in GHA

[snuyanzin]

What is the purpose of the change

The main idea: if there are only changes in tests, then skip non related jobs in GHA

for instance: if there is a test change in module table then skip others
if there are test changes in module core and table, then run jobs only for these 2
if there is a not only test change in any place then run everything as before
(examples in my fork

1. changes only in tests of table module: https://github.com/snuyanzin/flink/actions/runs/27491394160
2. changes in tests in table and formats https://github.com/snuyanzin/flink/actions/runs/27491450535
3. changes in tests table, formats and e2e https://github.com/snuyanzin/flink/actions/runs/27491962097
4. changes in e2e only https://github.com/snuyanzin/flink/actions/runs/27491434907
5. changes in non test code https://github.com/snuyanzin/flink/actions/runs/27491407658 )
