Merge pull request #5456 from shuujii/support-load-64-bit-integer-from-mrb-format-with-MRB_32BIT-and-MRB_INT64

Support load 64-bit integer from mrb format with MRB_32BIT and MRB_INT64

This change allows `def hello = puts "Hello"` without parentheses.
This syntax has been introduced since Ruby3.1.

Consistent number conversion function names:
* `mrb_value` to immediate (C) value
  * `mrb_int()` -> `mrb_as_int()`
  * `mrb_to_flo()` -> `mrb_as_float()`
* `mrb_value` to `mrb_value` (converted)
  * `mrb_to_int()'
  * `mrb_Integer()` - removed
  * `mrb_Float()` -> `mrb_to_float`

Consistent function name (avoid `_flo` suffix):
* `mrb_div_flo()` -> `mrb_div_float`

To be consistent, functions with `rational_` prefix implements methods,
functions with `rat_` prefix are utility functions.

The Ruby version of `Array#rotate!` generated a rotated array and
replaced the receiver, but the C version rotates the receiver array
in-place. So the performance is improved a lot both in speed and memory
consumption. Look for the comments in `array.c` for the in-place rotating
algorithm, if you are interested.

To avoid editor coloring failures.

Mostly for performance reason.

So that auto indentation works.

- move `TRUE/FALSE` definition from `mrbconf.h` (not configurable)
- use C/C++ definition of boolean type for `mrb_bool`

The fix is originally written by @take-cheeze.

build(deps): bump github/super-linter from 3.17.0 to 3.17.1

`mrb_int` may not fit in `fixnum` (inline integer).

Bumps [github/super-linter](https://github.com/github/super-linter) from 3.17.0 to 3.17.1.

Instead, copy them from the outer frame as CRuby does.

The performance of `Enumerable#entries` are significantly slower than
`Array#to_a`.

Except for compatibility code.

- `puts` behavior changed as CRuby
- fix wrong behavior in re-raising in `rescue`

`gettimeofday` emulation needed no longer.

Extend the tab with 8 whitespace

Order the EditorConfig properties

`Symbol#name` is similar to `#to_s` but returns a frozen string.

This work was done as follows:
- check:   `git grep $'\011' -- :^oss-fuzz`
- convert: `ruby -pi -e 'nil while $_.sub!(/^(.*?)\t/) { $1 + " " * (8 - $1.size % 8) }'`

The `doc/guide/{compile,mrbgems}.md` file adds and removes whitespace to make the directory tree look the same.
In `mrbgems/mruby-socket/src/socket.c`, there is a part where the indent is changed from 4 to 2 at the same time as the tab is changed.
