  [mlir][spirv][tosa] Add remaining TOSA 1.0 SPIR-V TOSA ops (#200383)

Add conversion patterns for additional TOSA 1.0 operations targeting the
SPIR-V TOSA extended instruction set.

This covers pooling and convolution ops, FFT/RFFT, matmul, concat, pad,
rescale, const, const_shape, and identity. Concat is split into
conservative chunks to avoid producing SPIR-V instructions with too many
operands.

Add a multi-result conversion pattern for FFT/RFFT and share the
convolution replacement logic for conv2d, conv3d, and depthwise_conv2d
while keeping transpose_conv2d explicit because it has different
attributes.

Also share constant attribute conversion for const and const_shape,
including integer element type conversions such as index to i32, i4 to
i8, and i48 to i64, and preserve the empty const_shape edge case.

Add conversion tests for the newly covered operations.
