[libc] add options to printf decimal floats
This patch adds three options for printf decimal long doubles, and these
can also apply to doubles.
1. Use a giant table which is fast and accurate, but takes up ~5MB).
2. Use dyadic floats for approximations, which only gives ~50 digits of
accuracy but is very fast.
3. Use large integers for approximations, which is accurate but very
slow.

[libc] add printf decimal float conversion
This patch adds support for converting doubles to string in the %f/F
format specifier. It does not yet support long doubles outside of the
double range. This implementation is based on the work of Ulf Adams,
specifically the Ryu Printf algorithm.
