Fix memory leaks in ext/sodium on failure of some functions

Infallible in practice right now, but should be fixed as infallible today does not mean infallible tomorrow:

Fallible today:

Use php_info_print_table_header for actual column headers only (#9485)

Using php_info_print_table_header() for "Foo: bar" looks odd and out of place,
because the whole line is colored. It is also questionable from a HTML
semantics point of view, because it does not described the columns that follow.

The use of this across extensions is inconsistent. It was part of the skeleton,
but ext/date or ext/json already use a regular row.

Add sodium_crypto_stream_xchacha20_xor_ic()

There are many use-cases where a PHP user is currently using sodium_compat's implementation of this low-level XChaCha20 API. For example, multi-part message processing (in low-memory settings) for a ciphertext that was encrypted with XChaCha20-Poly1305 (rather than the secretstream API).

Adding this function to ext/sodium offers better performance and lowers users' memory usage with the polyfill, and ensures that users coming from other languages that provide libsodium bindings have a more consistent experience with our bindings. This is a win-win.

This patch follows the libsodium precedent of adding functions instead of optional parameters to existing functions. The parameter order is also consistent with the C API.

Closes GH-8276.

Improve ristretto255 scalarmult exception messages

The $L value contained one extra null byte. The number of "false"
return values was too small.

scalar_invert() doesn't return a valid point -- not sure on that
one.

Add crypto_stream_xchacha20 to ext/sodium (#6868)

Paragon Initiative Enterprises is aware of PHP applications that use sodium_compat's ParagonIE\Sodium\Core\XChaCha20 class directly for stream encryption.

Greater performance and security assurance is offered by exposing libsodium's crypto_stream_xchacha20 API to PHP users.

It's acceptable to only include this change in PHP 8.1+; the offending applications are more than welcome to either install ext/sodium from PECL or upgrade to 8.1 when it comes out later this year.
