Some header files, specifically for OSX and Musl libc define PAGE_SIZE to be a number
This is great except in citra we're using PAGE_SIZE as a variable
Specific example
`static constexpr u64 PAGE_SIZE = u64(1) << PAGE_BITS;`
PAGE_SIZE PAGE_BITS PAGE_MASK are all similar variables.
Simply deleted the underscores, and then added CITRA_ prefix
* Make Citra build with MICROPROFILE_ENABLED set to 0
* Buildfix with microprofile kept on
* moc did not like a dialog to conditionally exist.
* Cleanup
* Fix end of line
