Do not compile philox_test.cpp test code if unnamed lambdas are not used

[mmichel11]

The recently added philox_test.cpp test does not do a preprocessor check if we are testing with unnamed lambda support, so we are seeing some compilation failures in CI.

I added this check. The rest of the Philox tests seem to be compiling fine.

I don't know enough about why we need to disable the RNG tests with unnamed lambdas off, but it seems this is the norm for the RNG tests.
Do we also need this for philox_unit_test.pass.cpp as well?
It seems that it calls return TestUtils::done(TEST_UNNAMED_LAMBDAS); but it does not actually skip the test with a preprocessor macro.
It seems like we need to add the guards, or change the done() call.

philox_unit_test doesn't contain any offload to devices, so it can be done with return TestUtils::done(TEST_UNNAMED_LAMBDAS); -> done() if it doesn't affect CI time significantly (I don't know in general when random numbers tests are run and when they are skipped)

Hi @mmichel11 , thanks for catching that. The issue was caused by my changes, I've fixed this thing and philox_unit_test.pass in a separate PR(#1820 ).
