Subject: [PATCH] Update SDL_gpu_textengine.c

fix: `error: declaration shadows a local variable [-Werror,-Wshadow]`

`AtlasGlyph *glyph;` is declared on line [623](https://github.com/libsdl-org/SDL_ttf/blob/db009130951541b4704c98e3ff4595dbced35dbe/src/SDL_gpu_textengine.c#L623) and then another variable with the same name is declared on line [633](https://github.com/libsdl-org/SDL_ttf/blob/db009130951541b4704c98e3ff4595dbced35dbe/src/SDL_gpu_textengine.c#L633).

Note: `AtlasGlyph *glyph;` is declared on line [623](https://github.com/libsdl-org/SDL_ttf/blob/db009130951541b4704c98e3ff4595dbced35dbe/src/SDL_gpu_textengine.c#L623) only because line [625](https://github.com/libsdl-org/SDL_ttf/blob/db009130951541b4704c98e3ff4595dbced35dbe/src/SDL_gpu_textengine.c#L625) uses it for sizeof in the malloc call.
