onedrive: default onedrive personal to QuickXorHash

Browse Source 
Before this change the hash used for Onedrive Personal was SHA1. From
July 2023 Microsoft is phasing out SHA1 hashes in favour of
QuickXorHash in Onedrive Personal. Onedrive Business and Sharepoint
remain using QuickXorHash as before.

This choice can be changed using the --onedrive-hash-type flag (and
config option) so that SHA1 can be selected while it is still
available in the transition period.

Before rclone 1.62 an SHA1 hash was used by default for Onedrive
Personal. For 1.62 and later the default is to use a QuickXorHash for
all onedrive types. If an SHA1 hash is desired then set this option
accordingly.
From July 2023 QuickXorHash will be the only available hash for
both OneDrive for Business and OneDriver Personal.
This can be set to "none" to not use any hashes.

Before rclone 1.62 the default hash for Onedrive Personal was `SHA1`.
For rclone 1.62 and above the default for all Onedrive backends is
`QuickXorHash`.
Starting from July 2023 `SHA1` support is being phased out in Onedrive
Personal in favour of `QuickXorHash`. If necessary the
`--onedrive-hash-type` flag (or `hash_type` config option) can be used
to select `SHA1` during the transition period if this is important
your workflow.
For all types of OneDrive you can use the `--checksum` flag.
