1. packages/lakka/libretro_cores/flycast/package.mk Enable GLES3 on RPi5.

2. projects/RPi/devices/RPi5/patches/flycast/0001-define-pagesize.patch In Case of RPi5, it changes "PAGE_SIZE" value from 4096 to 16384. This modification is for flycast GitHub issue #1288. And, it also has relationship flycast GitHub commit "linux: retrieve page size at build time". In this commit, "Will not work if cross-compiling however" is written. If the cross-compiling issue will be fixed in upstream, this patch file may be unnecessary.
