Define bold, italics and mono fonts in editor log for print_rich()

[Calinou]

Follow-up to #60675.

This is also used by the number indicator for message grouping, as it uses a bold font.

Mono font does not actually turn proportional fonts into monospace. Instead, it's a more faint version of the regular font, intended to emulate the look of the "faint" ANSI escape code (and make [code] distinguishable from regular text).

The custom code font will be used to generate the bold/italic/mono variants if specified in the Editor Settings.

Testing project: test_print_rich.zip

Preview

The font used here is Recursive Mono Casual, but this also works with the default editor code font.

Editor log

Editor log (custom font, Recursive Mono Casual Regular)

Terminal (VS Code)

Uses ANSI escape codes instead of BBCode.

This specific use case asks for an extra font option to prevent advance changes when embolden is used (to have all font variants with the same fixed width), but it's probably an overkill.

why make this workaround instead of use the same fonts created previously in this method, in example:

	Ref<FontFile> default_font_bold = load_internal_font(_font_NotoSans_Bold, _font_NotoSans_Bold_size, font_hinting, font_antialiased, true, font_subpixel_positioning, false);
	Ref<FontFile> default_font_bold_msdf = load_internal_font(_font_NotoSans_Bold, _font_NotoSans_Bold_size, font_hinting, font_antialiased, true, font_subpixel_positioning, true);

These fonts are not fixed-width, so they're not consistent with the rest of the editor Output panel's font (which is a code font by default).

Looks ok. It makes sense to add these fonts, to make print_rich() more complete.
