[MetaSchedule] Fix tune_tir crash with ScheduleError in 
RewriteParallelVectorizeUnroll (#18547)

This patch fixes issue #18423 where meta_schedule.tune_tir crashes
during initial population sampling when RewriteParallelVectorizeUnroll
postprocessor encounters blocks that violate compact dataflow
requirements.

The crash occurred when:
- A block reads and writes to the same buffer
- RewriteParallelVectorizeUnroll tries to parallelize/vectorize these
loops
- ScheduleError is thrown and propagates through parallel_for_dynamic

Solution:
- Added exception handling in RewriteParallelVectorizeUnroll::Apply to
catch ScheduleError and skip problematic blocks instead of crashing
- Added exception handling in ThreadedTraceApply::Apply to catch
exceptions from postprocessors and treat them as normal failures

This makes the tuning process more robust by gracefully handling
schedule errors instead of crashing the entire tuning session.
