[mlir] Enhance TimingManager Printing Flexibility (#85821)
Revise the printing functionality of TimingManager to accommodate
various output formats. At present, TimingManager is limited to
outputting data solely in plain text format. To overcome this
limitation, I have introduced an abstract class that serves as the
foundation for printing. This approach allows users to implement
additional output formats by extending this abstract class. As part of
this update, I have integrated support for JSON as a new output format,
enhancing the ease of parsing for subsequent processing scripts.
