Tests: set build directory using build type

Similar to {rB0a5f7061369d53b4eac55362ad2}
but also for Xcode and Ninja multi-config.

This silences 44 pairs of warnings like:

/bin/rm -f build_full/bin/tests/BLI_ghash_performance_test
"build_full/CMakeScripts/XCODE_DEPEND_HELPER.make:42: warning:
ignoring old commands for target
`build_full/bin/tests/BLI_ghash_performance_test'"

/bin/rm -f build_full/bin/tests/BLI_ghash_performance_test
"build_full/CMakeScripts/XCODE_DEPEND_HELPER.make:3523: warning:
overriding commands for target
`build_full/bin/tests/BLI_ghash_performance_test'"
