Revert "AVX-512: Handle curly braces in multi-line macro parameters"

This reverts commit a800aed7b75d56114f2e1e4928cbc48ecf96a4a0.

As recommended by the community, braces inside a group parameter
of multi-line macro should be parsed without a need of a leading
escape character such as "\{ab,c\}".
