[Picolibc] Version 1.4.4

[Keith Packard]

This is mostly a release to fix a bug in 'g' printf output caused by the
ryu printf changes. Seeing '1e+01' instead of '10' was somewhat
surprising.

### Picolibc version 1.4.4

 1. Fix floating point 'g' format output in tinystdio. (e.g.,
    for 10.0, print '10' instead of '1e+01'). There are tests which
    verify a range of 'g' cases like these now.
    
 2. Merge current newlib bits. The only thing which affects picolibc
    is the addition of fenv support for arm.
