Akanksha Mahajan cc24ac14eb Store FSSequentialFilePtr object in SequenceFileReader (#7190)
Summary:
This diff contains following changes:
    1. Replace `FSSequentialFile` pointer with `FSSequentialFilePtr` object that wraps `FSSequentialFile` pointer in `SequenceFileReader`.

Objective: If tracing is enabled, `FSSequentialFilePtr` returns `FSSequentialFileTracingWrapper` pointer that includes all necessary information in `IORecord` and calls underlying FileSystem and invokes `IOTracer` to dump that record in a binary file. If tracing is disabled then, underlying `FileSystem` pointer is returned directly. `FSSequentialFilePtr` wrapper class is added to bypass the `FSSequentialFileTracingWrapper` when tracing is disabled.

Test Plan:
make check -j64
          COMPILE_WITH_TSAN=1 make check -j64
