PHP 8.5 fixes and updates

All tested with PHP 8.4 and PHP 8.3 too

Major changes:
- cube root Math (cbrt) now throws InvalidArgumentException if NAN is returned instead of returning NAN
- Byte convert from string to int will throw errors if value is too large (\LengthException)
- new flag for returning string type but for this bcmath must be installed (\RuntimeException if no bcmath)
- Updated curl class and remove close handler as not needed and deprecated as of PHP 8.5
- Curl phpunit tests: convert string to JSON convert flow for return content check (to avoid per PHP version check)
- image close handler for ImageMagick removed as not needed and deprecated as of PHP 8.5
- updated all check calls too use phive tools if possible (except phpunit) and all scripts can have dynamic php version set
