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
