fmt: refactor pointer formatting and improve tests

Uses a switch statement for direct format function selection
similar to other types verb handling in fmt.

Applies padding also to nil pointers formatted with %v.

Guards against "slice bounds out of range" panic in TestSprintf
when a pointer test results in a formatted string s
that is shorter than the index i the pointer should appear in.

Adds more and rearranges tests.

Fixes #14712
Fixes #14714
