Picolibc version 1.8.2

• Support _ZEPHYR_SOURCE macro which, like _POSIX_SOURCE et al, controls whether the library expresses the Zephyr C library API. This is also automatically selected when the __ZEPHYR__ macro is defined and no other _*_SOURCE macro is defined.

• Add another cross compile property, 'libgcc', which specifies the library containing soft float and other compiler support routines.

• Fix a couple of minor imprecisions in pow and 80-bit powl.

• Merge newlib changes that included an update to the ARM assembly code.

• Replace inexact float/string conversion code with smaller code that doesn't use floating point operations to save additional space on soft float targets.

• More cmake fixes, including making the inexact printf and locale options work.
