[Bug #19793]
Dummy frames are created at the top level when requiring another file.
While requiring a file, it will try to convert using encodings. Some of
these encodings will not respond to to_str. If method_missing is
redefined on Object, then it will call method_missing and attempt raise
an error. However, the iseq is invalid as it's a dummy frame so it will
write an invalid iseq to the created NoMethodError.
The following script crashes:
```
GC.stress = true
class Object
public :method_missing
end
File.write("/tmp/empty.rb", "")
require "/tmp/empty.rb"
```
With the following backtrace:
```

Followup: ac123f167a364c3d7a43eca78d564e41f6dbb91e
RB_WARN_CATEGORY_ALL_BITS is exposed in a public header, so it
makes sense for it to be updated to contain all valid bits.
Instead we introduce RB_WARN_CATEGORY_DEFAULT_BITS to list the
categories that are enabled by default.

* If the receiver is a Class, use "... for class <class name>".
* If the receiver is a Module, use "... for module <module name>".
* If the receiver is an extended object (i.e., has a singleton class),
use "... for <rb_any_to_s(receiver)>".
* Otherwise, use "... for an instance of <class name>".
Examples:
```
42.time #=> undefined method `time' for an instance of Integer (NoMethodError)
class Foo
privatee #=> undefined local variable or method 'privatee' for class Foo (NoMethodError)
end
def (o=Object.new).foo
end
o.bar #=> undefined method `bar' for #<Object: 0xdeadbeef(any_to_s)> (NoMethodError)

An error message is primarily rendered in a terminal emulator, but is
also shown in a browser by converting it to a HTML fragment.
However, the conversion would be unreasonably difficult if the message
includes any escape sequence (such as cursor move or screen clear).
This change adds a guideline about escape sequences in
`Exception#detailed_message`:
* Use widely-supported escape sequences: bold, underline, and basic
eight foreground colors (except white and black).
* Make the message readable if all escape sequences are ignored.

Since enabling YJIT or MJIT drastically changes what could go wrong at
runtime, it's good to be front and center about whether they are enabled
when dumping a crash report. Previously, `RUBY_DESCRIPTION` and the
description printed when crashing can be different when a JIT is on.
Introduce a new internal data global, `rb_dynamic_description`, and set
it to be the same as `RUBY_DESCRIPTION` during initialization; use it
when crashing.
* version.c: Init_ruby_description(): Initialize and use
`rb_dynamic_description`.
* error.c: Change crash reports to use `rb_dynamic_description`.
* ruby.c: Call `Init_ruby_description()` earlier. Slightly more work
for when we exit right after printing the description but that
was deemed acceptable.
* include/ruby/version.h: Talk about how JIT info is not in
`ruby_description`.
* test/-ext-/bug_reporter/test_bug_reporter.rb: Remove handling for
crash description being different from `RUBY_DESCRIPTION`.
* test/ruby/test_rubyoptions.rb: ditto

Also, the default error printer and Exception#full_message use the
method instead of `Exception#message` to get the message string.
`Exception#detailed_message` calls `Exception#message`, decorates and
returns the result. It adds some escape sequences to highlight, and the
class name of the exception to the end of the first line of the message.

Factor out from rb_error_write the responsibility to check if stderr is
a tty.

Check that there is a method entry for the method before passing
it to rb_method_entry_arity.
