Added use_cropbox parameter to rasterize_pdf_page hook to allow
choosing between MediaBox and CropBox rendering:
- Default is use_cropbox=False (MediaBox) for consistency with
Ghostscript's existing behavior
- Ghostscript: passes -dUseCropBox when use_cropbox=True
- pypdfium: calculates crop values to expand from CropBox to MediaBox
when use_cropbox=False
This aligns both rasterizers to produce the same output dimensions
by default, making the rasterizer choice transparent for page
geometry.

pypdfium2/PDFium is not thread-safe - concurrent calls from different
threads can crash or corrupt the process. Added a module-level lock to
serialize all pdfium operations.
PIL image processing and file I/O are done outside the lock since they
are thread-safe, minimizing lock contention.
For maximum parallelism, users can use process-based parallelism
(use_threads=False) where each process has its own pdfium instance.

Add test_rasterizer.py with tests covering:
- Basic rasterizer option validation ('auto', 'ghostscript', 'pypdfium')
- Rasterizer + --rotate-pages interaction
- PDFs with nonstandard MediaBox/TrimBox/CropBox
- Direct hook tests verifying plugins respect the option
Also fix pluggy parameter passing: make 'options' a required parameter
(no default) in the hookspec so pluggy forwards it to implementations.
Update test plugins and test_rotation.py to pass the new parameter.

Before 42ff7fc842, `make_rotate_test`
always used `resources / 'typewriter.png'`, but after the change the
second call accidentally used just `resources`, which is a directory,
and fails to open.
Full message
eportlab/lib/rl_safe_eval.py:11: DeprecationWarning: ast.NameConstant is deprecated and will be removed in Python 3.14; use ast.Constant instead
haveNameConstant = hasattr(ast,'NameConstant')
Warning triggered by reportlab-4.0.7 and Python 3.12
This is mainly to permit the use of --tesseract-timeout 0 as a way of
disabling OCR but still allowing deskew and orientation detection to work.
The better solution will be introducing an explicit argument to
"don't ocr my pdf", but that will take more rework.
The parameters are equivalent but the latter is better named. Since
Python 3.6 doesn't support text= we use our wrapper to add it in that
place.
This is for subprocess.run.
