Had to split `core/io/zip_io.h` into header and .cpp file without 'static' keyword.
Not fixed yet (static definition in header used in some files but not all):
```
modules/websocket/lws_helper.h:111:13: warning: 'void _lws_make_protocols(void*, int (*)(lws*, lws_callback_reasons, void*, void*, size_t), PoolVector<String>, _LWSRef**)' defined but not used [-Wunused-function]
```
Also fixed a couple other warnings missed in previous commits.
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.

Fixes#15787.
The issue occurred when two (or more) separate DynamicFont instances
used the same DynamicFontAtSize instance due to having equal
properties. The first instance updated its data_at_size and emitted
"changed" signal, but the second did not because it considered the
data_at_size to be up to date, even though it has just been updated.
- Implement outlines based on FreeType Stroker API. This allows
artifact-free results, similar to what you will see in Web or any text
editing tools. Outline is a part of DynamicFont rather than Label,
because outlines have to be baked into the font's atlas. Font has a
default outline_color and a Label can specify font_outline_modulator
that will be multiplied with the Font's color to get the final result.
- draw_char now has to be called twice to fully render a text - first
with p_outline == true for each character and then with
p_outline == false for each character.
- Number of draw-calls is reduced from 5 to 2 per outlined character.
- Overall cleanup of DynamicFont code, extracted duplicated code pieces
into separate methods.
- The change is backward-compatible - Labels still have outline
properties that work exactly as they worked before.
Closes#16279.
They work exactly the same as current checkbox-decorated items, but in order to preserve compatibility, separate methods are used, like `add_radio_check_item()`. The other option would have been to add a new parameter at the end of `add_check_item()` and the like, but that would have forced callers to provide the defaults manually.
`is_item_checkable()`, `is_item_checked()` and `set_item_checked()` are used regardless the item is set to look as check box or radio button.
Keeping check in the name adds an additional clue about these facts.
Closes#13055.
