tcg: Make gen_dup_i32/i64() public as tcg_gen_dup_i32/i64

The Arm MVE VDUP implementation would like to be able to emit code to
duplicate a byte or halfword value into an i32.  We have code to do
this already in tcg-op-gvec.c, so all we need to do is make the
functions global.

For consistency with other functions made available to the frontends:
 * we rename to tcg_gen_dup_*
 * we expose both the _i32 and _i64 forms
 * we provide the #define for a _tl form
