This is the issue that tracks incomplete support for buffer overlap, so
we should refer to it when we discuss partial support whenever
MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS is set.

Mention that arbitrary overlap is now supported, except whenever
MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS is set.

Specifically:
* Clarify that passing shared buffers is now secure by default (not
newly supported)
* Remove spurious hyphen
* Clarify that we do not guarantee copying, but rather guarantee
protection, allowing us to implement this differently in future if
required.
* Mention both protection of inputs from modification and outputs from
exposure of intermediate results.
* Invert the config option, from an enable-option to a disable-option.
