I18N: Prevent PHP 8.5 float-to-int warnings in WP_Translation_File_MO.

On PHP 8.5+, large unsigned 32-bit integers returned by unpack() may be represented as floats on some platforms. Subsequent implicit casting can trigger warnings such as:

"The float 2500072158 is not representable as an int, cast occurred"

This patch introduces a helper method to normalize unpacked uint32 values and applies it to header and entry offsets before comparisons and arithmetic operations.

This ensures consistent unsigned 32-bit handling and prevents float-to-int casting warnings while maintaining existing behavior on both 32-bit and 64-bit platforms.

Note that 32-bit PHP is not really supported by WordPress any more - there are known serious issues with it like #63099.
