[libc][math] Implement exp10f function correctly rounded to all rounding modes.

Implement exp10f function correctly rounded to all rounding modes.

Algorithm: perform range reduction to reduce
```
  10^x = 2^(hi + mid) * 10^lo
```
where:
```
  hi is an integer,
  0 <= mid * 2^5 < 2^5
  -log10(2) / 2^6 <= lo <= log10(2) / 2^6
```
Then `2^mid` is stored in a table of 32 entries and the product `2^hi * 2^mid` is
performed by adding `hi` into the exponent field of `2^mid`.
`10^lo` is then approximated by a degree-5 minimax polynomials generated by Sollya with:
```
  > P = fpminimax((10^x - 1)/x, 4, [|D...|], [-log10(2)/64. log10(2)/64]);
```
