* Refactor CPU options for exacting common part between qemu and spike.
* Inject CPU options to spike run command line.

The below common CPU options are extracted to common part.

* xlen
* vlen
* extensions

The above CPU options will be leveraged to build the run arguments for
both the qemu and spike, for example.

QEMU: qemu-riscv64 -cpu rv64,v=true,vlen=1024,elen=64,vext_spec=v1.0
SPIKE: spike --isa=rv64imafdcv_zicsr_zifencei_zmmul --varch=vlen:1024,elen:64

Extend semantic for option '--with-extra-multilib-test'

Signed-off-by: Pan Li <pan2.li@intel.com>

The `--with-extra-multilib-test` take the format like below for now.

"<arch>-<abi>-[code-model][;<arch>-<abi>-[code-model]*"

This patch would like to extend the sematic to support additional buil
options for each combination. Aka:

"<arch>-<abi>-[code-model][:opts]*[;<arch>-<abi>-[code-model][:opts]*]*"

opts can be one or more build options splited by ':'. For example as
below:

* --param=riscv-autovec-lmul=m1
* --param=riscv-autovec-lmul=dynamic:--param=riscv-autovec-preference=fixed-vlmax

Thus the full example of the option `--with-extra-multilib-test` will be:

`rv64gcv_zvl128b-lp64d:--param=riscv-autovec-lmul=m1;rv64gcv_zvl256b-lp64d:-
-param=riscv-autovec-lmul=dynamic:--param=riscv-autovec-preference=fixed-vlmax`

Bump QEMU to v8.1.0

Add --with-extra-multilib-test option

Specify vector spec v1.0 in QEMU arguments.

Remove unused frameworks to give CI more disk space

Some testcases in GCC's testsuite check stdout.
Qemu will print a warning if the vector spec is not specified which will cause those testcases to fail.

The warning:
vector version is not specified, use the default value v1.0

NOTE: This is toolchain developer facing feature.

This allow user to add extra testing multi-lib arch, it's useful when
develop and/or testing new extensions.

Usage:

--with-extra-multilib-test="arch-abi[;arch-abi]"

e.g.

linux enable enabled multilib, so default will build with follwoing
configuration:

lib32/ilp32;@march=rv32imac@mabi=ilp32
lib32/ilp32d;@march=rv32imafdc@mabi=ilp32d
lib64/lp64;@march=rv64imac@mabi=lp64
lib64/lp64d;@march=rv64imafdc@mabi=lp64d

But you want to testing more on vector stuffs like rv32gcv and rv64gcv,
then you can configure with `--with-extra-multilib-test="rv32gcv-ilp32d;rv64gcv;lp64d"`

Then the testing will run rv32imac-ilp32 rv32imafdc-ilp32d
rv64imac-lp64 rv64imafdc-lp64d and rv32gcv-ilp32d;rv64gcv;lp64d!

NOTE: Extra multilib test settings still require existing
multilib has support those extra settings, e.g. you can't add
rv32imafc_zbb-ilp32f on above example since no compatible multilib has
provided.
