Summary of changes:

1. Set MarkForCompilationPassFlags::tf_xla_cpu_global_jit default to true in
C_API unit test env when XLA-execute is intended. Together with setting session
config config.graph_options.optimizer_options.global_jit_level to > 0, this
turns on XLA for the entire graph (eligible nodes only, with _Arg and _RetVal
nodes excluded).

We decided against defaulting MarkForCompilationPassFlags::tf_xla_cpu_global_jit
to true, due to performance concerns with the single-threaded nature of the XLA
CPU backend (see
https://www.tensorflow.org/performance/xla/jit#turning_on_jit_compilation).

2. In FindCompilationCandidates() during MarkForCompilationPass, skip compiling
any '_Arg'-typed nodes. This is necessary to avoid hitting a "Invalid argument
number" error during MarkForCompilationPass.

test "CAPI.Session_Min_XLA_CPU".
