Use common function for TypeError on illegal offset access (#10544)

This merges all usages of emitting an offset TypeError into a new ZEND_API function
zend_illegal_container_offset(const zend_string* container, const zval *offset, int type);

Where the container should represent the type on which the access is attempted (e.g. string, array)
The offset zval that is used, where the error message will display its type
The type of access, which should be a BP_VAR_* constant, to get special message for isset/empty/unset

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.

Introduce convenience macros for copying flags that hold when concatenating two strings

This abstracts away, and cleans up, the flag handling for properties of
strings that hold when concatenating two strings if they both hold that
property. (These macros also work with simply copies of strings because
a copy of a string can be considered a concatenation with the empty
string.) This gets rid of some branches and some repetitive code, and
leaves room for adding more flags like these in the future.
