[PR] test(parquet): reduce macOS race test memory pressure [arrow-go]

zeroshade opened a new pull request, #1275:
URL: https://github.com/apache/arrow-go/pull/1275

   ### Rationale for this change
   
   The macOS test jobs run on 7 GB ARM64 runners and intermittently kill `parquet/file` while running under the race detector. Two large-value regression tests each write more than 1 GB and retained all encoded output in memory. Package-level parallelism adds further pressure.
   
   Example failure: https://github.com/apache/arrow-go/actions/runs/33590782213/job/100362942846?pr=1241
   
   ### What changes are included in this PR?
   
   - Replace the retained `bytes.Buffer` output in the two large-value tests with a counting writer.
   - Run Parquet packages serially (`-p=1`) on Darwin to bound package-level memory pressure.
   - Correct both macOS job names from AMD64 to ARM64.
   
   ### Are these changes tested?
   
   - `go test -race -tags assert ./parquet/file -count=1`
   - `go test -race -tags assert,noasm ./parquet/file -count=1`
   - `bash -n ci/scripts/test.sh`
   - `git diff --check`
   
   Both formerly high-memory tests also passed independently under `-race -tags assert,noasm`.
   
   ### Are there any user-facing changes?
   
   No.
