python-pycparser: bump to 3.0

v3.0 removes the dependency on PLY by rewriting pycparser with a
hand-written lexer and recursive-descent parser for C. No API changes
or functionality changes - the same AST is produced as before.

Other changes:
- Drop EOL Python 3.8 and 3.9 support (minimum now 3.10)
- Add support for Python 3.14

Since PLY is no longer used:
- Remove python-ply from PKG_BUILD_DEPENDS and HOST_BUILD_DEPENDS
- Remove +python3-ply from package DEPENDS
- Remove 001-use-external-ply.patch (no longer needed)
