Instead of forcing use of NEWLIB_LIBC, select any available complete C
library implementation. Add CONFIG_REQUIRES_FLOAT_PRINTF where needed.

The malloc arena/heap size setting can be adjusted using different
Kconfig options, depending on the libc implementation. This means
prj.conf can't be used to set this value on projects that can be built
for multiple libcs without generating a Kconfig warning.
Note: similar fix was applied for the hash_map sample, see

With picolibc moving to using the common malloc implementation, samples and
tests with picolibc-specific settings need to switch to using the common
malloc settings instead.

With the minimal C library malloc implementation moving to libc/common, all
of the related Kconfig variables have also changed. Update uses within the
tree.
