Refactor BCMath bundledlib and extension (#10774)
* ext/bcmath: coding style: use indentation

And add braces to block statements, as the current code was pretty much unreadable with how inconsistent it was.

* ext/bcmath: Remove some useless header inclusions

* ext/bcmath: Use standard C99 bool type instead of char

* ext/bcmath: Include specific headers instead of config.h

* Restructure definitions to reduce header inclusions

* Use size_t as a more appropriate type

* Remove unused variable full_scale

* Refactor bc_raisemod() to get rid of Zend dependencies

This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library

* Refactor bc_raise() to get rid of Zend dependencies

This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library

* Refactor bc_divmod() and bc_modulo() to return bool

Return false on division by 0 attempt instead of -1 and true on success instead of 0

* Refactor bc_divide() to return bool

Return false on division by 0 attempt instead of -1 and true on success instead of 0
