[PATCH v6 0/1] Optimizing the print format of the QEMU monitor 'info mtree'

[Chao Liu <lc00631@tecorigin.com>]

Hi, all:

Thanks to BALATON, and David for their reviews.

In PATCH v6:
1. Replaced the bool type with enum mtree_node_type to improve code readability.
2. Modified the output to use only one horizontal dash instead of two, and
   aligned character printing for a cleaner look.

like this:

```
$ ./qemu-system-aarch64 -S -monitor stdio -M raspi4b
(qemu) info mtree
address-space: memory
`- 0000000000000000-ffffffffffffffff (prio 0, i/o): system

...

PATCH v5 changelog:
1. Fix one comment, level 0 no longer prints line characters.

PATCH v4 changelog:
1. When printing the child nodes of a single node, the line characters from the
   parent node's level are no longer printed, making the output more concise
   and clear overall;
2. Use more commonly used ASCII characters, such as '|--' instead of '├──',
   and '`--' instead of '└──';
3. Control the number of prefix characters to reduce unnecessary output;

PATCH v3 changelog:
1. Use more maintainable c functions instead of macros, as per review comments.

PATCH v2 changelog:
1. Enrich the commit message, add 'info mtree' print example.
2. Optimize the code implementation according to the review comments.
