Trim `BorrowedCursor` API
This PR removes some method from the unstable `BorrowedCursor` type. A rational for each change can be found in the message of each commit.
I don't think that an ACP is required for this, please tell me if it is not the case.

core: Add `BorrowedCursor::with_unfilled_buf`
Implementation of https://github.com/rust-lang/libs-team/issues/367.
This mainly adds `BorrowedCursor::with_unfilled_buf`, with enables using the unfilled part of a cursor as a `BorrowedBuf`.
Note that unlike the ACP, `BorrowedCursor::unfilled_buf` was moved to a `From` conversion. This is more consistent with other ways of creating a `BorrowedBuf` and hides a bit this conversion that requires unsafe code to be used correctly.

core: Change `BorrowedCursor::written`'s origin2025-07-09T16:11:27+00:00Benoît du Garreaubenoit@dugarreau.fr2025-07-09T16:11:27+00:00urn:sha1:65df66831f3fdb7f20a74e843a46bb90993221eb
This enable removing the `start` field, so `BorrowedCursor` fits in a
single register. Because `written` is almost always used in difference
with another call, this changes nothing else in practice.
core: Remove `BorrowedCursor::uninit_mut`2025-07-09T16:11:26+00:00Benoît du Garreaubenoit@dugarreau.fr2025-07-09T16:11:26+00:00urn:sha1:34555f1b0b49e4fd944b2cb9c298f15b6b5da144
I assume that this method was there for completeness, but there is
hardly any useful use of it: the buffer it gave was not always connected
to the start of the cursor and its use required `unsafe` anyway to mark
the bytes as initialized.
core: Remove `BorrowedCursor::init_ref` method2025-07-09T16:11:26+00:00Benoît du Garreaubenoit@dugarreau.fr2025-07-09T16:11:26+00:00urn:sha1:803b4d262241b22a4dfe75fcec49eaf920e0816b
This method was not really useful: at no point one would only need to
read the initialized part of the cursor without mutating it.
