[PATCH 1/2] docs: programming-language: remove mention of the Intel compiler

[Miguel Ojeda]

The Intel compiler support has been removed in commit 95207db8166a
("Remove Intel compiler support").

Thus remove its mention in the Documentation too.

[PATCH 2/2] docs: programming-language: add Rust programming language section

[Miguel Ojeda]

Following the C text in the file, add a mention about the Rust
programming language, the currently supported compiler and
the edition used (similar to the "dialect" mention for C).

Similarly, add a mention about the unstable features used (similar
to the "extensions" mentions for C).

In addition, add some links to complement the information.
