Use compressed debug symbols

The size of file will be greater than 2G in Debug and RelWithDebug mode.

The use of compressed debug symbols significantly reduces library size,
avoiding the need to remove targets in the address sanitizer build.
The non-address sanitizer debug builds didn't drop GPU targets, but
shared the same library size problem as the address sanitizer build.
This change will also fix those builds.
