[tint][bench]: Fix MSL benchmarks 

These required binding point remapping so that the @group is always zero.

Also: Use a unique_ptr for the file in ProgramAndFile. Previously the diagnostics were referring to the std::moved file, causing segfaults if the benchmark program errors and printed diagnostics.
