[poly2tri] Set policy CMP0063 to NEW (#27263)

Browse Source 
* Set policy CMP0063 to NEW

This change enables CMake to set the symbol visibility of static
libraries. Since poly2tri is compiled as a static library, without this
change, it can lead to linker warnings about conflicting visibility
settings if it is itself linked into a dynamic library.

* fixup! Set policy CMP0063 to NEW

* amend! Set policy CMP0063 to NEW

Set default symbol visibility to hidden

Policy CMP0063 enables CMake to set the symbol visibility of static
libraries. Since poly2tri is compiled as a static library, without this
change, the default symbol visibility cannot be set, leading to linker
warnings about conflicting visibility settings if poly2tri is itself
linked into a dynamic library.
