[backend](fix) remove lib-call no-inline option (#1923)

Stop passing --enable-lib-call-no-inline=false to bishengir-compile for Ascend950 targets. The explicit override changes vendor code generation and regresses kernels that worked before it was introduced.

Remove the target and compiler-capability helpers that were only used to append this option.
