Import as-is much of the old "Patches" wiki page to the current
sending_patches.rst file. This means we need to move patman to being
included in the higher level ToC and add a reference for "Custodians" in
the process document. A very minimal amount of content changing and
rewording is done here as part of the import, in order to make the
conversion easier.

These will be expanded as development proceeds.

Start by describing in general the best practices for how to implement
configuration of some aspect of U-Boot.  This generally means finding
the right choices for when something should be static or dynamically
configured and enabled.  Then further document when to use CONFIG or CFG
namespaces for static configuration.

Migrate the RelaseCycle wiki page to Sphinx.  In terms of visible
changes, we stop having a dynamic countdown to when the release is.  And
we drop the year-based statistics, that were not being kept up to date.
For the moment, we only link to statistics for v2022.07 but will add
back the historical data in a subsequent patch.

Move the current Process wiki page to doc/develop/process.rst.  The
