[PATCH v2 02/83] rust: block: rename `SECTOR_MASK` to `PAGE_SECTOR_MASK`

[Andreas Hindborg]

The constant exposes `bindings::SECTOR_MASK`, which masks the sector
index within a page (`PAGE_SIZE / SECTOR_SIZE - 1`), not `SECTOR_SIZE`
itself as the original docstring suggested. The misleading name made
it easy for callers to reach for it when they wanted a byte-level
sector mask.

Rename the Rust constant to `PAGE_SECTOR_MASK` and fix the docstring.
The C binding is unchanged.
