[roll] Roll fuchsia [kernel][phys] Introduce RISC-V feature set abstraction

This change introduces arch::RiscvFeatures, a container abstraction
around the set of RISC-V features of interest to the kernel. This is
populated in phys as the lowest common denominator of features across
all hart ISA strings and is included in the hand-off.

As a first use, the kernel's RISC-V feature detection constants -
previously hardcoded to true in wait of a programmatic means to query
this info - are updated to be defined in terms of the new handed-off
feature abstraction.

This will be soon be used to conditionalize support for select RISC-V
features in the kernel.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
