[vcpkg] add updated compile wrapper for clang-cl

[Neumann-A]

has already been merged upstream but I have no clue when it will be in automake from msys.
The relevant change is line 259.

Alternatively we could just patch the msys download? But where should those patches be stored?

I am concerned about the potential licensing implications of this. Is it unreasonable to wait for msys?

I feared that that would be the answer. So where should I store the patch for msys ? ;)

scripts/msys/xyz.patch; vcpkg_acquire_msys() then can apply the patch after un-tarring all the packages together but before renaming if it detects that the automake package was requested.

@ras0219-msft: Done.

Thanks!

@dg0yt Couldn't you also patch libtool with this? Or am I pinging the wrong person.

[dg0yt]

@Neumann-A libtool is considered external and not accepted as a port.

didn't you have changes to bash scripts which could now be patched into vcpkg_acquire_msys ?

@Neumann-A Sorry, the PR title was unable to convey the information that this PR contains relevant changes, such as a PATCHES option.
