[Cherry-Pick] Add Log double grad kernel (#27604)

 double grad support for abs 

* add batch norm double grad, test=release/1.8

* update, test=develop

* fix, test=develop

* optimize slice TRT plugin

This patch removes unnecessary barrier for data transfer of needed offset,
so data transfer can be overlap with GPU kernel execution.

This patch also fixes incorrect name of slice plugin. That is, replaces
"layernorm" with "slice"
