feat(proguard): Bump proguard to 5.10.1 and filter synthesized frames

[romtsn]

Summary

• Bumps proguard crate from 5.9.0 to 5.10.0
• Filters out compiler-synthesized frames (e.g. lambda bridges) from remapped stacktraces, matching R8 retrace behavior
• Handles StackFrame::line() now returning Option<usize> instead of usize
• Fixes incomplete test mapping for outline callsite position entries
• Updates integration test snapshots for new filename/abs_path fields

Currently blocked by getsentry/rust-proguard#88 which needs to be shipped in a patch release and bumped here to make the CI pass

Test plan

• Unit tests updated and passing
• Integration test snapshots updated
• Verify CI passes

Autofix Details

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Symbolication stats count frames later dropped by filtering
  • Moved symbolicated_frames counting to after synthesized-frame filtering so only retained frames are counted.
