Embedded function pointer is prohibited under serialization.

In PRONTOLab/GB-25#29 (comment) @giordano observes a segmentation fault, the issue is that

Reactant.jl/src/xla/PJRT/LoadedExecutable.jl

Line 131 in 0cfcef7

call void inttoptr ($ptr $fn to void ($ptr, $cint, [$N x $ptr]*, $extra_str1, [$M x i8]*, $cint, [$n_outs x $ptr]*, i8*, [$n_outs x $ptr]*)*)($ptr %exec, $cint $N, [$N x $ptr]* nocapture readonly %inpa, $extra_str2, [$M x i8]* nocapture readonly %dona, $cint $n_outs, [$n_outs x $ptr]* nocapture writeonly %outa, i8* nocapture writeonly %futa, [$n_outs x $ptr]* nocapture writeonly %futpa)

Is embedding a runtime function pointer obtained from dlsym. Probably what we need to do here is to just use an "external symbol" and the dlopen the runtime globally?
