Expand coverage of unary ops

[bddppq]

Added support for:
aten::cos
aten::acos
aten::cosh
aten::sin
aten::asin
aten::sinh
aten::tan
aten::atan
aten::abs
aten::floor
aten::reciprocal
aten::ceil
aten::exp
aten::neg

Also replaced previous conversion rule of aten::sqrt that uses trt Scale.

The changes look good, ran the converter test suite and it fails due to there no longer being a scale test. I think all you need to do is remove the scale test from //tests/core/converters/BUILD

Oops forgot to remove the deleted test, fixed now.
