Use 'constexpr' when including pio header files from a C++ compiler (#2651) 
* Use 'constexpr' when including pio header files from a C++ compiler

In particular this allows compile-time checks to be performed on the
contents of pio_program structs via 'static_assert'.

This could be used (for example) to confirm that multiple PIO programs
fit in a single PIO module and abort compilation if not.

Fixes #2650

* Use feature test macro to check for 'constexpr' support

* Rename modifier PIO_CONST to __pio_const
