Fix load the font which the name contains unicode text

[lindexi]

Description of Change

I change the string input argument from string to IntPtr. The sk_fontmgr_match_family_style should input the utf8 encoding string, but we will input the Unicode16 string to it. That is why we can not load the font which the font name contains the unicode text, such as the Chinese font.

Bugs Fixed

• Fixes [BUG] sk_fontmgr_match_family_style must input family name argument by utf8 string #1914

API Changes

None.

Behavioral Changes

Now, we can load the font which the font name contains unicode text, such as the Chinese font.

Required skia PR

None.

Thanks for this PR and catching those unicode issues!

The SkiaApi.generated.cs is generated by the tools, so these changes will get overwritten. You should rather edit the json file and then re-run the generator: https://github.com/mono/SkiaSharp/tree/main/utils#generate

I absolutely butchered the merge, so the commit is not so great. Sorry about that - had to create a special merge commit on that: 6f8fc4d
