ReleaseNotes: Improve organization and other minor fixes

Browse Source 
Improve organization by sorting architectures and boards into alphabetical
order. Improve consistency of newlines between headings and contents. In
sections that include subsections for new features and bugfixes, list the
new features (or major/significant improvements) first, followed by
bugfixes. In Compatibility Concerns section, rewrap the lines and add
backticks around identifiers that should print in a fixed-width typeface.

## Changes to Build System
### Change CFLAGS, CPPFLAGS, CXXFLAGS, and AFLAGS from Recursive to Simple Assignment
[PR-1890](https://github.com/apache/incubator-nuttx/pull/1890) (commit [2caf3a69e3d60ec550980f7ba897c732e7a39df7](https://github.com/apache/incubator-nuttx/pull/1890/commits/2caf3a69e3d60ec550980f7ba897c732e7a39df7)) attempts to speed up compilation time for concurrent builds by changing assignment to makefile variables *CFLAGS*, *CPPFLAGS*, *CXXFLAGS*, and *AFLAGS* from recursive `=` to simple `:=`. This causes these compile options to be expanded only once during the build.

attempts to speed up compilation time for concurrent builds by changing
assignment to makefile variables `*CFLAGS*`, `*CPPFLAGS*`, `*CXXFLAGS*`, and
`*AFLAGS*` from recursive `=` to simple `:=`. This causes these compile
options to be expanded only once during the build.
If you are using NuttX on a custom board not in the NuttX repository, you may
want to make a similar change to your `Make.defs` files. Change these
recursive assignments:

CXXFLAGS = $(ARCHCXXFLAGS) $(ARCHWARNINGSXX) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
CPPFLAGS = $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS)

### Not Necessary to Define `__NuttX__` in Make.defs
[PR-2192](https://github.com/apache/incubator-nuttx/pull/2192) (commit [9208176f600d0d04446531909bf05710716a5ee4](https://github.com/apache/incubator-nuttx/commit/9208176f600d0d04446531909bf05710716a5ee4)) refactors definition of the `__NuttX__` preprocessor symbol to `tools/Config.mk`, so it is no longer necessary to define it in each board's Make.defs file.

Remove lines like this:
```
ARCHDEFINES = -D__NuttX__
```
Or remove -D__NuttX__ from lines like this:
```
CXXFLAGS += $(ARCHDEFINES) $(EXTRAFLAGS) -pipe -std=c++11 -D__NuttX__
```
