Documentation: describe how to apply incremental stable patches

The applying patches document
(Documentation/process/applying-patches.rst) mentions incremental stable
patches, but there is no example of how to apply them. Describe the
process.

While at it, remove note about incremental patches and move the external
link of 5.x.y incremental patches to "Where can I download patches?"
section.

If no 5.x.y kernel is available, then the highest numbered 5.x kernel is
the current stable kernel.

The -stable team provides normal as well as incremental patches. Below is
how to apply these patches.
The -stable team usually do make incremental patches available as well
as patches against the latest mainline release, but I only cover the
non-incremental ones below. The incremental ones can be found at

Normal patches
~~~~~~~~~~~~~~
These patches are not incremental, meaning that for example the 5.7.3
patch does not apply on top of the 5.7.2 kernel source, but rather on top

Incremental patches
~~~~~~~~~~~~~~~~~~~
Incremental patches are different: instead of being applied on top
of base 5.x kernel, they are applied on top of previous stable kernel
(5.x.y-1).
Here's the example to apply these::
$ cd ~/linux-5.7.2 # change to the kernel source dir
$ patch -p1 < ../patch-5.7.2-3 # apply the new 5.7.3 patch
$ cd ..
$ mv linux-5.7.2 linux-5.7.3 # rename the kernel source dir
