[DWARF] Avoid entry_values production for SCE

SONY debugger does not prefer debug entry values feature, so
the plan is to avoid production of the entry values
by default when the tuning is SCE debugger.

The feature still can be enabled with the -debug-entry-values
option for the testing/development purposes.

This patch addresses PR46643.
