Reduce PDB size for storage_grpc feature

[cuiy0006]

We got

LINK : fatal error LNK1201: error writing to program database 'C:\b\google\cloud\storage\benchmarks\storage_throughput_vs_cpu_benchmark.pdb'; check for insufficient disk space, invalid path, or insufficient privilege

when building core feature for storage_grpc in debug mode.

We cannot use larger runner because the cost is high.

We need to research any way to reduce the PDB size of storage_grpc debug build.

Some thoughts,

1. Using specific linker flags can strip unnecessary information from the PDB.

target_link_options(your_target PRIVATE "/PDBSTRIPPED" "/PDBCOMPRESS")

2. Ensure that debug information is not generated at the compilation stage if it's not needed.

target_compile_options(your_target PRIVATE "/Zi")
