Xtensa requires building a new toolchain for a specific SoC.
By default xtools built Xtensa toolchains all have prefix of
xtensa-zephyr-elf. In order to distinguish different toolchains,
they are now placed in their own directories under their SoC
name. This allows us to have multiple Xtensa toolchains
targeting multiple SoCs.
The additional level in path name is introduced in SDK v0.11
and sdk-ng master.

This adds the necessary bits to build the Xtensa HAL as
a module, and removes the bits to use the HAL built with
the Zephyr SDK.

Since x86_64-zephyr-elf is a multi-lib toolchain, m32/m64
need to be specified for the compiler to return the correct
library path when queried (e.g. --print-libgcc-file-name).
This affects the compile check done by CMake. Without these
flags, the compiler returns incorrect toolchain path (e.g.
requiring 64-bit libraries but returning 32-bit library path).
This also affects compiler flag checks for "-lstdc++". Incorrect
library path results in error when checking for "-lstdc++", and
this flag will not be used for the build. This results in
undefined references when compiling C++ code.
This creates target_x86.cmake to add the necessary flags for
CMake to use. The target_x86_64.cmake is also created to
mirror the same change.
Also removing the -m32 flags for host-gcc since we are not
building x86 targets with the host-gcc compiler.

The target.cmake for xtools needs to be updated for changes in
sdk-ng repo. This is simply a copy from the target.cmake for
0.10 SDK.

There are two set of code supporting x86_64: x86_64 using x32 ABI,
and x86 long mode, and this consolidates both into one x86_64
architecture and SoC supporting truly 64-bit mode.
() Removes the x86_64:x32 architecture and SoC, and replaces
them with the existing x86 long mode arch and SoC.
() Replace qemu_x86_64 with qemu_x86_long as qemu_x86_64.
() Updates samples and tests to remove reference to
qemu_x86_long.
() Renames CONFIG_X86_LONGMODE to CONFIG_X86_64.

With the upcoming riscv64 support, it is best to use "riscv" as the
subdirectory name and common symbols as riscv32 and riscv64 support
code is almost identical. Then later decide whether 32-bit or 64-bit
compilation is wanted.
Redirects for the web documentation are also included.
Then zephyrbot complained about this:
"
New files added that are not covered in CODEOWNERS:
dts/riscv/microsemi-miv.dtsi
dts/riscv/riscv32-fe310.dtsi
Please add one or more entries in the CODEOWNERS file to cover
those files
"
So I assigned them to those who created them. Feel free to readjust
as necessary.

This adds the necessary bits to utilize the x86_64 toolchain
built by sdk-ng for x86_64 when toolchain variant is either
zephyr or xtools. This allows decoupling the builds from
the host toolchain.
Newlib is also available with this toolchain so remove
the Kconfig restriction on CONFIG_NEWLIB_LIBC.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Xtensa toolchain has a HAL library that needs to be compiled in similar
to how we do this with the Zephyr SDK.

Split up the toolchain configuration into two phases, generic and
target. The 'generic' phase configures the toolchain just enough to be
able to preprocess DT files. The 'target' phase completes the
configuration with target-specific configuration.
