rust: update the rust-cpython crate to 0.7.0
This notably brings support for Python 3.10, and includes the panic message
when propagating a Rust panic as a Python exception.

dirstate-v2: Name a constant in the Rust implementation
We are about to introduce a Python version of this code that will also need
this constant.

dirstate-v2: Replace the 32-bit `mode` field with two bits
Previously we stored the entire value from `stat_result.st_mode`,
like dirstate-v1 does. However only the executable permission
and type of file (only symbolic links and normal files are supported)
are relevant to Mecurial.
So replace this field with two bits in the existing bitfield byte.
For now the unused space is left as padding, as it will be used
for something else soon.

dirstate-v2: Truncate directory mtimes to 31 bits of seconds
… instead of 64 bits, while keeping the sub-second presision.
This brings the size of one timestamp from 12 bytes to 8 bytes.
31 bits is chosen instead of 32 because that’s already what happens for the
mtime of files and symlinks, because dirstate-v1 uses negative i32 values as
markers.
Later we’ll add sub-second precision for file/symlink mtimes, making their
dirstate-v2 representation the same as for directories.

dirstate-v2: Separate Rust structs for Timestamp and PackedTimestamp
PackedTimestamp is now exclusively for dirstate-v2 serialization purpose.
It contains unaligned big-endian integers. Timestamp is used everywhere else
and contains native Rust integers.
