When early_data extension is enabled and sent in ClientHello,
the client does not know if the server will accept early data
and select the first proposed pre-shared key with a ciphersuite
that is different from the ciphersuite associated to the selected
pre-shared key. To address aforementioned case, we do associated
verification when parsing early_data ext in EncryptedExtensions.
Therefore we have to assign the ciphersuite in current handshake
to session_negotiate later than the associated verification.
This won't impact decryption of EncryptedExtensions since we
compute handshake keys by the ciphersuite in handshake not via
the one in session_negotiate.

The official spelling of the trade mark changed from all-lowercase "mbed"
to normal proper noun capitalization "Mbed" a few years ago. We've been
using the new spelling in new text but still have the old spelling in a
lot of text. This commit updates most occurrences of "mbed TLS":
```
sed -i -e 's/mbed TLS/Mbed TLS/g' $(git ls-files ':!ChangeLog' ':!tests/data_files/**' ':!tests/suites/*.data' ':!programs/x509/*' ':!configs/tfm*')
```
Justification for the omissions:
* `ChangeLog`: historical text.
* `test/data_files/**`, `tests/suites/*.data`, `programs/x509/*`: many
occurrences are significant names in certificates and such. Changing
the spelling would invalidate many signatures and tests.
* `configs/tfm*`: this is an imported file. We'll follow the upstream
updates.

Introducing an intermediate function
saves code size that's otherwise taken by excessive,
repeated arguments in each place that
was translating errors.

Large static inline functions used from several translation units in the
library are bad for code size as we end up with multiple copies. Use the
actual function instead. There's already a comment that says so.

As usual, just a search-and-replace plus:
1. Removing things from hash_info.[ch]
2. Adding new auto-enable MD_LIGHT in build-info.h
3. Including md_psa.h where needed

Move in a dedicated function the search for the
supported_versions extension in a list of
extensions, to be able to use it on server side
as well.
