Support symbolized odex preopt output

Add support for generating symbolized .odex output alongside existing
stripped .odex output for dexpreopt'ed targets. This creates the
symbolized artifact in the same output intermediate directory as its
stripped counterpart with a `.symbols.odex` suffix.

A follow-up change will collect and archive these symbolized artifacts
alongside other comparable preopted artifacts.

Bug: 342009826
Test: m CredentialManager + inspect intermediate `symbols.odex` output
