[x265] [PATCH] cmake: switch to c++11 for Clang and GCC

[Mateusz Brzostek]

After tests with GCC from 4.8 to 8.0 I think it is OK to change to c++11 from c++98 (for -DENABLE_DYNAMIC_HDR10=ON and OFF).

Selur (Hybrid author) wrote that for Clang it should be c++11 instead of gnu++11, so we can set for Clang c++11, for GCC gnu++11.

Please review.
