The can_fetch_default variable needs to be set before the call to
_ep_write_gitupdate_script(). Move it to before that call and always
set the variable, even if arg_SCRIPT_FILE is not set. This makes the
generated git update script file easier to follow if someone tries to
follow what it is doing or wants to investigate problems and run it
manually.

In commit da5de7f9f3 (bootstrap: Allow --boostrap-system-* libraries
custom prefixes, 2024-03-03, v3.30.0-rc1~456^2) the non-pkg-config code
path for uv/jsoncpp/rhash all set `use_librhash_ldflags` instead of
their own variable.
In 462e583267 (ExternalProject: Switch download, update and patch to
use _EP_ vars, 2024-05-13), the svn_username and svn_password variables
were only updated appropriately in the svn download implementation, but
not in the svn update implementation. This was easily missed in part
because the old implementation was relying on behavior that differed
from the documentation for get_property(), and the new implementation
tried to keep the intermediate variables from the old implementation but
missed this subtle aspect.

Skip the `CMAKE_OSX_ARCHITECTURES` validation added by commit db409e5e68
(APPLE: Check if compilers respect CMAKE_OSX_ARCHITECTURES, 2024-05-04,
v3.30.0-rc1~15^2) if the value contains a placeholder, since we do not
know the real value.

First, use `cmGeneratedFileStream` to avoid touching an existing file
unless its contents change and to get atomic replacement. Also add a
scope to ensure that the file is in place (at `fout`'s destructor)
before doing anything with the packaging scripts.

Since commit 67de5b7b82 (VS: Suppress MSBuild default settings affected
by UseDebugLibraries, 2024-02-13, v3.30.0-rc1~538^2~1) we generate an
empty `Optimization` element for the host compiler when there are no C
or C++ optimization flags enabled. The CUDA Toolkit Visual Studio
integration fails with an error if an empty string is inherited from the
host compiler's `Optimization` element. If no CUDA optimization flags
are specified, write an explicit empty `Optimization` element for the
CUDA compiler too.

Since commit d3cbee99e3 (macOS: Prefer building with system-provided
curl, 2024-05-09, v3.30.0-rc1~130^2~1) CMake uses the macOS-provided
curl, which uses the LibreSSL backend by default. This exposes us to
curl issue 12525, created and fixed by the following upstream curl
commits:
* commit `bec0c5bbf` (openssl: switch to modern init for
LibreSSL 2.7.0+, 2023-08-07, `curl-8_3_0~201`)
* commit `9f2d2290d` (openssl: re-match LibreSSL deinit with init,
2023-12-15, `curl-8_6_0~219`)
Work around the bug by preferring the secure-transport backend by
default on the problematic versions of curl.
These were missed in commit e0355c4ea9 (FindBoost: Add policy to remove
this module, 2024-05-03, v3.30.0-rc1~150^2) and commit 0aba13a2f3
(ctest: Add explicit options for TLS server verification, 2024-03-01,
v3.30.0-rc1~408^2~3).
Revise commit 657064b6d4 (FindMatlab: Refactor: Eliminate
_matlab_64Build, 2024-01-24, v3.30.0-rc1~594^2~5) to more faithfully
reproduce the original behavior.
Revise commit 91c672e5ae (FindMatlab: Use find_package(Threads) instead
of checking -pthread, 2024-02-02, v3.30.0-rc1~594^2~1) to restore the
old behavior of looking for threads only with C or CXX enabled.
Fixes: #26121
Since commit c16acd35b3 (GenEx: Add support for custom transitive link
properties, 2024-05-09, v3.30.0-rc1~82^2) evaluation of
`TRANSITIVE_LINK_PROPERTIES` by `install(EXPORT)` enables discovery of
missing dependencies on INTERFACE libraries that we did not previously
diagnose. This regressed existing projects that relied on such
non-diagnosis. Although commit 2fc9e482a9 (Evaluation of
TRANSITIVE_LINK_PROPERTIES isn't considered a usage, 2024-07-05) fixed
this, it also made a significant change to the `UseTo` infrastructure
that may have other subtle effects. Replace the fix with an approach
that explicitly models suppression of the relevant diagnostics.

Move Git-dependent test cases added by commit 2ef3bd9186
(ExternalProject: Add TLS version options for https connections,
2024-02-26, v3.30.0-rc1~471^2) into the block of cases that run only
when Git is found.
