Migrate check_op_args.h validations to meta kernels and remove it (#19207)

[mcremon-meta]

Summary:

Move operator argument validation from runtime C++ checks (check_op_args.h) to
AOT meta kernels (ops_registrations.py), enabling compile-time error detection
and reducing on-device binary size.

• Delete check_op_args.h (~3,244 lines) and check_macros.h (~175 lines)
• Add torch._check() validation to ~50 meta kernels in ops_registrations.py
  covering dtype, dimension, shape, and scalar parameter constraints
• Inline the 4 data-dependent runtime checks (division-by-zero, attention_mask
  bounds) directly into kernel implementations across generic, HiFi, and G3
  backends
• Remove codegen wrapper generation from codegen.py (generate_wrapper_code,
  insert_runtime_context, etc.) since checks no longer need wrapper functions
• Update ops.bzl to remove wrapper.cpp references and wrapper library creation
• Update targets.bzl to remove deleted header references
