Remove GetAt from string classes
This method duplicates the behaviour of the const [] operator and
doesn't offer any additional safety. Folding them into one
implementation.
SetAt is retained, since implementing the non-const [] operator to
replace SetAt has potential performance concerns. Specifically many
non-obvious cases of reading an element using [] will cause a realloc
& copy.
