Since presym is now mandatory, mruby.h includes presym.h so that
MRB_SYM() macros are available everywhere without explicit include.
Remove redundant #include <mruby/presym.h> from all source files.

Replace check_method_noarg() with check_argument_count() that validates
min <= argc <= max using the full aspec stored in mrb_method_t.flags.
This catches ArgumentError earlier at dispatch time, before entering
the C function.
The old check only handled the special case of aspec==0 (NOARG).
The new check extracts REQ, OPT, REST, POST, KEY, and KDICT from
the aspec and validates accordingly. Keyword hash is counted as
a positional arg only when the method doesn't accept keywords.
Remove MRB_METHOD_NOARG_P macro from proc.h (subsumed by aspec check).
Fix 15 incorrect aspec declarations across the codebase that were
exposed by the stricter enforcement.

Added complete call-seq documentation for all errno module methods in
mrblib/errno.rb (3 methods):
## Errno Module Methods:
- const_defined?: checks if errno constant exists on the system, provides
dynamic errno constant detection by querying both system-defined errno
values and superclass constants with proper boolean return values
- const_missing: handles dynamic errno constant definition when undefined
constants are referenced, automatically defines errno classes for valid
system error codes and delegates to superclass for invalid names
- constants: returns array of all available errno constant names on the
system, includes both already defined constants and those that can be
dynamically defined, with dependency note for mruby-metaprog gem

Added complete call-seq documentation for public methods and corrected
internal method documentation structure:
Public API methods
- SystemCallError.new: Create SystemCallError with message/errno
- SystemCallError#errno: Get errno number from exception
- SystemCallError._sys_fail: Internal method to raise errno exceptions
- Errno exception classes#new: Create specific errno exceptions
Fixed documentation structure to follow mruby conventions where internal
methods starting with __ should not have call-seq documentation but only
brief explanatory comments.
Each public method now includes:
- Clear method signatures with parameter and return types
- Descriptions of errno handling behavior
- Practical examples showing exception creation and handling
- Consistent formatting following mruby documentation standards

If the `Errno::EXXX` class is defined minimally when needed, it will save about 17 KiB of RAM in a 32-bit environment.
Define the singular methods `.const_defined?`, `.const_missing` and `.constants` in the `Errno` module and act as if there are classes that have not yet been defined.
However, if real classes are enumerated, for example by the following code, the effect is lost.
```ruby
Errno.constants.map { |id| Errno.const_get(id) }
```
But I believe that such codes are rarely written with the intention of being written.
In this patch, the `Errno::EXXX#initialize` method is no longer defined for further memory reduction.
Instead, it has been merged into the `SystemCallError#initialize` method.
Internal functions can only be called from within the library.
Functions listed in `mruby/internal.h` can be called from:
* core (src/*.c)
* gems (mrbgems/**/*.c)
But not from the application linked with `libmruby`.
The `mrbgems/mruby-errno/src/known_errors_def.cstub` file has been extended, so the `mrbgems/mruby-errno/src/known_errors_e2c.cstub` file is no longer needed.
ref. #2485
The `SystemCallError#to_s` method also needed to be modified, but since it has no functional difference from the `Exception#to_s` method, it will be removed.
