Improve performance String#index with UTF-8
...
Based on Boyer-Moore-Horspool algorithm (Quick Search algorithm).
As a side effect, the correct position is returned even if an invalid UTF-8
string is given.
```console
% ./mruby@master -e 'p ("\xd1" * 100 + "#").index("#")'
50
% ./mruby@improve-index -e 'p ("\xd1" * 100 + "#").index("#")'
100
```
The other behavior should be the same as the current implementation.

Rename MRB_STR_NO_UTF to 'MRB_STR_ASCII`; close #4550
...
In #4550 , @shuuji proposed the name name `MRB_STR_NO_MULTI_BYTE` for
more precise description. Although I agree that the name name is
correct, but the flag means the string does not contain multi byte UTF-8
characters, i.e. all characters fit in the range of ASCII.

Change to UTF-8 string reversing with in place
...
Reverses UTF-8 strings without allocated heap for working memory.
1. String before reversing:
```
"!yburmの界世"
# byte unit
[33, 121, 98, 117, 114, 109, 227, 129, 174, 231, 149, 140, 228, 184, 150]
```
2. Reverse the byte order of each character:
```
[33, 121, 98, 117, 114, 109, 174, 129, 227, 140, 149, 231, 150, 184, 228]
```
3. Reverse the whole byte order and complete:
```
[228, 184, 150, 231, 149, 140, 227, 129, 174, 109, 114, 117, 98, 121, 33]

For example on 32 bit mode, when `p = 0xfffffffd`, `e = 0xfffffffe`

with `e` will to be false.
As a result, a segmentation fault occurs by referring to address 0.

We have removed implicit conversion to strings using `to_str`. But some
people still using `to_str` as a typical string method, i.e. they do
string check by code like: `obj.respond_to?(:to_str)`. So we have
recovered the method.
