[C++] parquet tools: linking error when ARROW_JSON=OFF with undefined reference to `arrow::json::JsonWriter::GetString() const'

[rouault]

Describe the bug, including details regarding any error messages, version, and platform.

Since c44eca6 ("#50779: [C++][Parquet] Replace remaining RapidJSON usage with simdjson (#50781)"), building with ARROW_JSON=OFF leads to:

[ 96%] Linking CXX executable ../../debug/parquet-dump-arrow-statistics
/usr/bin/ld: ../../debug/libparquetOFF.so.2600.0.0: undefined reference to `arrow::json::JsonWriter::GetString() const'
/usr/bin/ld: ../../debug/libparquetOFF.so.2600.0.0: undefined reference to `arrow::json::JsonWriter::String(std::basic_string_view<char, std::char_traits<char> >)'

Also affects projects linking with libparquet such as GDAL in https://github.com/OSGeo/gdal/actions/runs/31694127460/job/94427940549

@rouault , i would like to work on this issue, if u r not working on this one.. u can assign me....

My approach would be to trace the JsonWriter symbol references introduced by the recent RapidJSON → simdjson migration, reproduce the failure with ARROW_JSON=OFF, identify the incorrect dependency/conditional compilation path, and add a regression test to ensure Parquet builds and links correctly with JSON disabled.
If no one is currently working on this, I’d be happy to take it up.

@rouault, if you're not currently working on this issue, could you please confirm? I can then assign it to @KHARSHAVARDHAN-eng.
