Remove usage of full_like/ones_like/zeros_like ops in eltwise composite where tensor-scalar support is available

[KalaivaniMCW]

In tt-eager,
Some of the eltwise-binary ops did not have tensor-scalar support, so eltwise composite/backward ops that were implemented used full_like/ones_like/zeros_like to convert scalar to tensor and pass it for binary operations.

• Since now we have #14172 , we can modify our implementations in various eltwise ops

• cleanup unary_composite

• cleanup binary_composite #14879

• cleanup ternary_composite #14880

• cleanup unary_backward #14713

• cleanup binary_backward #14714

• cleanup ternary_backward

• cleanup complex

• cleanup complex backward
