opcache: Do not disable userland error handlers in opcache_compile_file()
The logic to disable userland error handlers existed since the first commit including OPcache in php-src. The reason unfortunately is not explained. No existing tests require that userland error handlers do not trigger in `opcache_compile_file()`. The newly added tests are intended to exercise all possible kinds of edge-cases that might arise and cause issues (e.g. throwing Exceptions, performing a bailout, or loading a different file from within the error handler). They all pass for both `--repeat 1` and `--repeat 2`, as well as with OPcache enabled and without OPcache enabled (in the latter case with the exception of the `opcache_get_status()` verification). The list of cached files at the end of execution also matches my expectations. Therefore it seems that disabling the userland error handler when compiling a file with OPcache is not (or at least no longer) necessary. Fixes #17422.
