Use custom nvbench entry point to ensure cudf::nvbench_base_fixture usage #13183

Description

Previously we used the nvbench::main CMake target which would cause the same main.o to re-used across targets.
Since this object file was compiled without any knowledge of rmm or libcudf it wouldn't have our custom NVBENCH_ENVIRONMENT type. This caused our benchmarks to not execute with the rmm pool allocator.
