[Tests] Add spec tests in FIR + LightTree configuration

In some tests PSI and LT differ. Test data was fixed accordingly.

In the following tests I consider that difference is acceptable:
- compiler/tests-spec/testData/diagnostics/linked/expressions/try-expression/p-1/neg/3.1.kt
- compiler/tests-spec/testData/diagnostics/linked/expressions/try-expression/p-1/neg/4.1.kt

This is because:
- It only happens when recovering from syntax errors happened above in
code. I was unable to reproduce it in valid code.
- It doesn't break parsing further, the rest of the errors in file are
reported identically.

The rest of the tests will be fixed in subsequent commits.
