[mlir][Linalg] emitLoopRanges and emitLoopRangesWithSymbols merged into one

Right now there is a branching for 2 functions based on whether target map has
symbols or not. In this commit these functions are merged into one.
Furthermore, emitting does not require inverse and map applying as it computes
the correct Range in a single step and thus reduces unnecessary overhead.
