49380b59d2 Fix #81679: Tracing JIT crashes on reattaching 
When a new process reattaches to OPcache, tracing JIT causes segfaults,
because each new process allocates its own `zend_jit_traces` and
`zend_jit_exit_groups` in SHM, although these need to be shared between
all processes.

We solve that by only allocating these structs for the first process,
and store the pointers in `accel_shared_globals`, so we can reassign
them when a new process reattaches.

Closes GH-7776.

0b3a937670 Fix GH-7759: Incorrect return types for hash() and hash_hmac() 
`hash()` and `hash_hmac()` never return `false`; only `hash_file()` and
`hash_hmac_file()` return `false` in case the data cannot be read.

Closes GH-7760.
