Commit c0a5c81ca9be ("Kconfig.debug: drop GCC 5+ version check for
DWARF5") could have cleaned up the code a bit more.

"CC_IS_CLANG &&" is unneeded. No functional change is intended.

CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT does not give explicit
-gdwarf-* flag. The actual DWARF version is up to the toolchain.

The combination of GCC and GAS works fine, and Clang with the integrated
assembler is good too.

The combination of Clang and GAS is tricky, but at least, the -g flag
works for Clang <=13, which defaults to DWARF v4.

Clang 14 switched its default to DWARF v5.

Now, CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT has the same issue as
addressed by commit 98cd6f521f10 ("Kconfig: allow explicit opt in to
DWARF v5").

CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y for Clang >= 14 and
GAS < 2.35 produces a ton of errors like follows:

  /tmp/main-c2741c.s: Assembler messages:
  /tmp/main-c2741c.s:109: Error: junk at end of line, first unrecognized character is `"'
  /tmp/main-c2741c.s:109: Error: file number less than one

Add 'depends on' to check toolchains.

Commit f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from
a choice") added CONFIG_DEBUG_INFO_NONE into the DWARF version choice,
but it should rather belong to the debug level choice.

This commit consolidates CONFIG options into two choices:

 - Debug info level (NONE / REDUCED / DEFAULT)

 - DWARF format (DWARF_TOOLCHAIN_DEFAULT / DWARF4 / DWARF5)

This is more consistent with compilers' policy because the -g0 compiler
flag means "no debug info".

  GCC manual:

    -g<level>

      Request debugging information and also use level to specify how
      much information. The default level is 2.

      Level 0 produces no debug information at all. Thus, -g0 negates -g.

      Level 1 produces minimal information, enough for making backtraces
      in parts of the program that you don’t plan to debug. ...

      Level 3 includes extra information, such as all the macro
      definitions present in the program. ...

  Rustc Codegen manual:

    debuginfo

      This flag controls the generation of debug information. It takes
      one of the following values:

      0: no debug info at all (the default).
      1: line tables only.
      2: full debug info.

I moved CONFIG_DEBUG_INFO_REDUCED into the debug level choice.

This change will make it easier to add another debug info level if
necessary.

Update defconfig files accordingly. This includes the fixes for commit
f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a choice").

The intent of this patch was a ground-work for adding
CONFIG_DEBUG_LEVEL_FULL or something, but
Dmitrii retracted the patch for macro debugging. [1]

I will not apply this for now.
If we get into a situation that needs more debug info,
let's revisit it.
