viable/strict/1780344791: Fix typos in comments, docstrings, and error messages (#185719)

Correct spelling and grammar errors across Python and C++ source files

in torch, including fixes like "rewrie" -> "rewrite", "it's" -> "its"

(possessive), "Mixing" -> "Mixin", "ospet" -> "opset", duplicate words,

and other minor textual issues. No functional changes.

Authored with Claude (typo_terminator2).
