Remove harmful and redundant bindings from the byte compiler.

Remove harmful and redundant bindings from the byte compiler.

This fixes bug#65017.  Binding symbols-with-pos-enabled in two
macro handling functions was harmful; one of these caused
cl--labels-convert to fail.  Binding print-symbols-bare in many
places in the byte compiler was redundant.

print-symbols-bare.

(internal-macroexpand-for-load): Remove bindings of
symbols-with-pos-enabled.
