Add torch.log10 INT support to ExecuTorch Arm backend (#18671)

[JorickvdHoeven]

Summary:

Adds quantized (INT) support for torch.log10 in the ExecuTorch Arm backend using the lookup table (LUT) path. TOSA has no native LOG10 op, so for quantized inference the op is handled via a precomputed table in the InsertTableOpsPass.

Changes:

• Registered log10.default in the unary_table_ops dict in insert_table_ops.py for the LUT quantized path
• Added log10.default to _one_to_one in quantization_annotator.py to enable quantization annotation
• Added log10.default to TOSA_PRO_INT_SupportList in tosa_profile_supported_op_lists.py so the partitioner delegates it to the Arm backend
• Wrote test/ops/test_log10.py with TOSA INT, U55 INT, and U85 INT test cases
• Registered the test in `test/targets.bzl
