sdcc: Added 4.5.0

[jhol]

This PR depends up #26578 first begin merged.

[jhol]

Ok, the build is finally fixed!

I'm feeding back the various issues to the developers here: https://sourceforge.net/p/sdcc/mailman/sdcc-devel/thread/1523c791c8ca91e0c642466d76ec8ec8%40airwebreathe.org.uk/#msg59270426

@jhol The following patch resolves the issue caused by #define B. The root cause is that a compilation error occurs if #define B appears before including winsock2.h, but not if it appears after. Testing shows that including windef.h before #define B prevents the compilation error. This patch includes cmdutil.h earlier in the file. Since cmdutil.h includes winsock2.h, it eliminates the issue related to #define B.

Additionally, I tested that sdcc can be compiled under clang64. build with clang need avoid ada check

  declare -a _extra_config
  if [[ ${MINGW_PACKAGE_PREFIX} == *-clang-* ]]; then
    # Checking for a working Ada compiler takes very long and ultimately fails.
    _extra_config+=("acx_cv_cc_gcc_supports_ada=no")

add treedec for sdcc #26852

[jhol]

Here is a v2 of the patch-set with @SquallATF 's suggestions:

• Fixes build issues with ucsim using the far simpler approach proposed by @SquallATF .
• Adds support for clang64 build.
  • clangarm64 isn't supported for now until aarch64-w64-mingw32 support is added to support/sdbinutils/bfd/config.bfd. Support for this platform was added in binutils 16fea92ccd99, which was released v2.41. clangarm64 support can be added once SDCC integrates this.

Here is v3 of the patch-set with a dependency on the treedec package added. ~~The CI system build will fail until the mingw-w64-treedec package has been built and uploaded, but~~ it has been tested locally. The SDCC configure script gives the following output:

checking for treedec/combinations.hpp... yes

[jhol]

Here is v4 of the patch which makes the following changes:

• Set SDCC license to SPDX identifier
• Set msys2_documentation_url, msys2_repository_url and msys2_references.

[ognevny]

is it ready now?

[jhol]

Here is v5 of the patch which makes the following changes:

• Address @ognevny 's review comments.
• Rebase on master

[jhol]

is it ready now?

I think so. There's no more changes planned from my side.
