matthewvon 4126bdc0e1 Feature: add SetBufferSize() so that managed size can be dynamic (#7961) ... Summary: This PR adds SetBufferSize() to the WriteBufferManager object. This enables user code to adjust the global budget for write_buffers based upon other memory conditions such as growth in table reader memory as the dataset grows. The buffer_size_ member variable is now atomic to match design of other changeable size_t members within WriteBufferManager. This change is useful as is. However, this change is also essential if someone decides they wanted to enable db_write_buffer_size modifications through the DB::SetOptions() API, i.e. no waste taking this as is. Any format / spacing changes are due to clang-format as required by check-in automation.
