[libcxx][CMake] Do not hard-code the ABI for the GPU build

jhuber6 · jhuber6 · commit 6d66ac51a49a · 2024-09-20T13:52:08.000-05:00
Summary:
We specify the ABI to experimental, but we should leave this up to the
user. Primarily this is because we want the ABI to be compatible with
the user's CPU build, so the default should be used.
