720982a3cb string: Quit early if --quiet is satisfied 
E.g. if we do `string match -q`, and we find a match, nothing about
the input can change anything, so we quit early.

This is mainly useful for performance, but it also allows `string`
with `-q` to be used with infinite input (e.g. `yes`).

Alternative to #7495.

5ddafb3b79 Add support for importing named regex matches 
The new commandline switch `string match --regex --import` will import
as fish variables any named capture groups with the matched captures as
the value(s).

f758d39535 string pad: handle padding characters of width > 1 
If the padding is not divisible by the char's width without remainder,
we pad the remainder with spaces, so the total width of the output is correct.

Also add completions, changelog entry, adjust documentation, add examples
with emoji and some tests.  Apply some minor style nitpicks and avoid extra
allocations of the input strings.

5ae03414d7 Sort string subcommands, and use binary search for lookup 
I have no idea if this is better, and did not attempt to measure it, but we
do the same for electric variables which are even fewer.

bcfc54fdaa Do not buffer builtin output if avoidable 
builtins output to stdout and stderr via io_streams_t. Prior to this fix, it
contained an output_stream_t which just wraps a buffer. So all builtin output
went to this buffer (except for eval).

Switch output_stream_t to become a new abstract class which can output to a
buffer, file descriptor, or nowhere. This allows for example `string` to stream
its output as it is produced, instead of buffering it.

3cfe113a60 builtin_string: Remove redundant condition in handle_flag_f 
The removed comparison ({begin,end,field} == INT_MIN) always evaluates
to false, because at this point in evaluation, `begin <= 0` has already
been evaluated to be false.  Since INT_MIN <= 0, the second conditional
in all three of the affected cases is always false.  The C++ standard
seems to guarantee left-to-right evaluation of logical operators, but
not necessarily bitwise operators.

08eac28bd8 Add individual documentation pages for string's subcommands 
This adds string-x.rst for each subcommand x of string. The main page
(string.rst) is not changed, except that examples are shown directly after
each subcommand.  The subcommand sections in string.rst are created by
textual inclusion of parts of the string-x.rst files.

Subcommand man pages can be viewed with either of:

```
man string collect
man string-collect
string collect <press F1 or Alt-h>
string collect -h
```

While `string -h ...` still prints the full help.

Closes #5968
