Enable building on arm64
This change allows source-build to be cloned and built on arm64 machines. It shouldn't affect cross compilation at all, however. I have tested this on RHEL 8 aarch64. This change includes backports of the following pull-requests which have been merged into their respective master branches: - dotnet/aspnetcore#14790 - dotnet/aspnetcore#15354 - dotnet/installer#4102 - dotnet/core-setup#8468 - dotnet/corefx#40453 There's a number of existing build configuration that are conditionalized on arm64, such as setting up a root file system. Those they are actually only meant to be invoked when cross-compiling for arm64 (on x86_64). This commit modifies those conditions to not apply when building on an arm64 machine.

Subject: [PATCH] Support global.json on arm64 as well
5+
6+
arcade uses the runtime section of global.json to decide which
7+
architecture + runtime combination needs to be installed.
8+
9+
With https://github.com/dotnet/arcade/pull/4132 arcade can install
10+
foreign SDKs in separate locations correctly.
11+
12+
This change, suggested by @dougbu, makes arcade always install the
13+
runtime for the local architecture (which means it should work on arm64
14+
and x64) as well as the x86 architecture (skipped on Linux).
15+
16+
This gets us a working SDK/Runtime combo on arm64.

Subject: [PATCH] Support building for arm64 on arm64 (*nix)
5+
6+
This commit allows ASP.NET Core to be built on arm64 machines directly,
7+
without relying on cross-compilation.
8+
9+
There's a few changes in here:
10+
11+
1. Ask msbuild to look into the BuildArchitecture
12+
13+
By default, our build systems assums the machine is x64. This
14+
modifies the build configuration to check the architecture of the
15+
currently running build machine, and set BuildArchitecture to that.
16+
17+
2. Fix crossgen in Microsoft.AspNetCore.App.Runtime
18+
19+
We run crossgen for supported architectures (including x64 and
20+
arm64). For that, we need a jit that we can point crossgen to.
21+
Generally, we can rely on the build scripts to find the right
22+
`libclrjit.so`. However, arm64 has multiple `libclirjit.so`, for
23+
different use-cases. There's one for arm64 (for running on arm64) and
24+
there's another one for cross-compiling for arm64 on x64. We need to
25+
figure out and use the right one explicitly rather than assuming the
26+
right one gets picked up.
27+
28+
See https://github.com/dotnet/core-setup/pull/8468 for similar
29+
changes made in core-setup.
30+
31+
This also needs https://github.com/aspnet/AspNetCore/pull/14790 to fully
32+
work on arm64.
