[Zend]: Fix unnecessary alignment in ZEND_CALL_FRAME_SLOT macro (#10988)

Alignment is not necessary while calculating slots reserved for
zend_execute_data and _zend_vm_stack.

ZEND_STATIC_ASSERT ensures the correct alignment while code
compilation. Credit is to Ilija Tovilo.

zend_compiler, ...: use `uint8_t` instead of `zend_uchar` (#10621)

`zend_uchar` suggests that the value is an ASCII character, but here,
it's about very small integers. This is misleading, so let's use a
C99 integer instead.

On all architectures currently supported by PHP, `zend_uchar` and
`uint8_t` are identical. This change is only about code readability.

Fix GH-10168: heap-buffer-overflow at zval_undefined_cv

The problem is that we're using the variable_ptr in the opcode handler
*after* it has already been destroyed. The solution is to create a
specialised version of zend_assign_to_variable which takes in two
destination zval pointers.
