Mark alpaka trait constants as inline

[fwyzard]

PR description:

Mark trait constants as inline, and simplify the definition of the trait types.

Fixes #39786.

PR validation:

GCC 11 now generates unique global symbols (u) instead of local data symbols (b) for the allocators:

/data/user/fwyzard/gcc11/CMSSW_12_6_0_pre3/src$ nm -C ../lib/el8_amd64_gcc11/libHeterogeneousCoreAlpakaServicesCudaAsync.so | egrep 'allocator$'
0000000000016400 u guard variable for cms::alpakatools::getHostCachingAllocator<alpaka::uniform_cuda_hip::detail::QueueUniformCudaHipRt<alpaka::ApiCudaRt, false>, void>()::allocator
0000000000016420 u cms::alpakatools::getHostCachingAllocator<alpaka::uniform_cuda_hip::detail::QueueUniformCudaHipRt<alpaka::ApiCudaRt, false>, void>()::allocator
