If a project() call does not have DESCRIPTION or HOMEPAGE_URL
options, it must still set the relevant variables or else those variables will
inherit values from an earlier project() call. That is inconsistent with how
VERSION is handled and is likely to be unexpected. The docs were also
ambiguous about what should happen in such cases.
When we set `CMAKE_<LANG>_COMPILER_TARGET` to the Android target
architecture, add it to `CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND` also.
This is needed to make moc predefines aware of `__ANDROID__`.

f17f22a2 Terminal: Add alacritty and alacritty-direct to VT100 color support whitelist
Use of `std::log10` added by commit 02c5091c90 (cmCTestRunTest: Simplify
number width computation, 2018-09-08) broke our number width computation
on some platforms where
static_cast<int>(std::log10(static_cast<size_t>(10)))
somehow produces `0` instead of `1`. Re-implement the logic to avoid
floating-point computations.
A that target contains only `.cs` sources should be generated as a
`.csproj` project even if it links to non-CSharp static libraries.
The latter case was broken by refactoring in commit v3.12.0-rc1~160^2~7
(remove TargetIsCSharpOnly() and use methods from cmGeneratorTarget,
2018-03-19). The reason is that the `HasLanguage` method added by
commit v3.12.0-rc1~239^2~6 (cmGeneratorTarget: add HasLanguage() as
wrapper for GetLanguages(), 2018-03-19) enforces its "exclusive" check
on the combined set of source file languages and the link language.
To restore the original `TargetIsCSharpOnly` semantics, update
`HasLanguage` to enforce exclusiveness only on the list of sources.
Fixes: #18239
When a CSharp target links to a static C++ library, CMake will compute
the link language as C++ instead of CSharp. That may be incorrect and
needs further investigation, but it does not affect how VS drives C#
linking. However, it does break our flag language selection logic
and causes C++ flags to be used for CSharp. In particular, this
drops the `-platform:x86` flag on 32-bit builds.
Fix this by always selecting the CSharp flags when generating a
`.csproj` project type.
