[NupharEP] symbolic_shape_infer improvements#2299

Conversation
This change improves symbolic shape inference in following ways: 1. Extend suggested merge to map to literals with --auto_merge. For example, MatMul of ['ax1', 'ax2'] x [128, 256] would now map 'ax2' to 128 2. Add --int_max option to simplify computations like Min(100000, 'dim') to be 'dim'. This helps ops like Slice to generate correct shape, i.e. start=0, end=Min(100000, dim - 2) on dim. It was previously treated as equal, since sympy cannot determine Min(100000, dim - 2) < dim. Besides, the change contains a bug fix for create_shared script on Windows, that AOT dll is not generated because of failure in link, when there are too many obj files. Plus, some build warning fixes for NupharEP.
