core(view): changes due to conversion from md to rst

[romintomasetti]

As mentioned in #569, I'll need the View.md to understand RST. So I need to renamed it. And so Sphinx complains.

Changes:

1. Sections, subsections and so on.
2. Code blocks.
3. References (to sections, footnote).
4. Italic.
5. The table becomes a csv-table.

@dalg24 @masterleinad The diff is still hard to read, even though I went over the Sphinx complains one by one (nothing more). What should we do ?

1. We don't care and proceed.
2. I do one commit per type of change (see description), so the PR diff will still be bad, but each separate commit will be more reviewable.

[masterleinad]

Looks good to me. Ignoring white space changes makes this not that hard to compare.

[dalg24]

Did you check that the output looks reasonable?

[masterleinad]

The documentation in the artifact looked fine to me. We could try to improve the accessibility matrix a bit and reference_is_lvalue should be reference_type_is_lvalue but we can address that in a follow-up since it's preexisting.
