302f5171d8 Utilities/Sphinx: Add 'cref' role
Add a role that can be used to create local links (a la '`LINK`_'), but
that also applies literal style. This is particularly useful for
referring to subcommands within the command's documentation in a style
that is consistent with ':command:`BAR <foo(BAR)>`' but is much less
verbose.

Although this is intended for subcommands, it works with any local
reference.

2e37a20f02 Utilities/Sphinx: Allow explicit target for genex
Split the genex directive into its own class, allowing a slight
simplification of CMakeObject. Add ability to specify an explicit target
name for the same.

Use this to provide a target for the `$<TARGET_PROPERTY:prop>` generator
expression which is otherwise missing one (due to overlap with
`$<TARGET_PROPERTY:tgt,prop>`).  With this one can write:

    :genex:`$<TARGET_PROPERTY:prop> <TARGET_PROPERTY:prop>`

to link the second variant.

39ecaa5da1 Utilities/Sphinx: Improve word wrap of signatures
Implement logic to support several styles of parsing in the new
signature directive that control where line breaks are allowed in a
signature.

The default is 'smart', which forbids breaks inside of square- or
angle-brackets. The 'verbatim' option forbids all breaks. In all cases,
breaks are always allowed where a newline appears in the source.

This seems to Just Work for most writers, but HTML needs some special
handling that is accomplished by a new CSS rule and assigning the 'nbsp'
class to spaces that are not allowed to break. (ROFF's line wrapping is
rather unfortunate here, as it prefers splitting and hyphenating words
rather than breaking at a space.)

cc21d0e478 Utilities/Sphinx: Make signatures linkable
Add signatures to the collection of observed objects (which can be
referenced elsewhere). Don't automatically strip parameters from a
:command: reference, as these may now link signatures. (Do, however,
munge them into 'text <ref>' form if they aren't already, as not doing
so adds an extra '()' for some reason.) Correspondingly, change xref
resolution to try to match 'command' when a ref like 'command(args)' is
not matched, so that existing links to commands that have not been
converted to use the new signature directive don't immediately break.

74e3c1d313 Utilities/Sphinx: Add a directive to document command signatures
Add a `signature` directive to offer a CMake version of Sphinx's
`function` directive, similar to that found in other domains (py, cpp,
etc.).  Like others, this takes one or more signatures as arguments and
creates dt/dd nodes from the signatures and the directive contents.

e84fcbcb0b cxxmodules: support new round of Clang patches
These patches now support the `-MF` output, so remove the `none` support
added just for the old patchset which did not use it.

Also update the flag name to `-fmodule-output=`.

Due to the new Clang module mapper flag, use a new experimental support
UUID as well.

386465bf83 cmTarget: add support for C++ module fileset types
C++ modules have two variants which are of importance to CMake:

  - `CXX_MODULES`: interface modules (those using `export module M;`,
    `export module M:part;`, or `module M:internal_part;`)
  - `CXX_MODULE_HEADER_UNITS`: importable header units

Creating C++ modules or partitions are *not* supported in any other
source listing. This is because the source files must be installed (so
their scope matters), but not part of usage requirements (what it means
for a module source to be injected into a consumer is not clear at this
moment). Due to the way `FILE_SET` works with scopes, they are a perfect
fit as long as `INTERFACE` is not allowed (which it is not).

4b23359117 ninja: Add experimental infrastructure for C++20 module dependency scanning
Optionally enable this infrastructure through an undocumented
`CMAKE_EXPERIMENTAL_CXX_MODULE_DYNDEP` variable.  Currently this is
experimental and intended for use by compiler writers to implement their
scanning tools.  Warn as such when the feature is activated.  Later when
compilers provide the needed scanning tools we can enable this variable
from our corresponding compiler information modules.  It is never meant
to be set by project code.

When enabled, generate a build graph similar to what we use for Fortran
module dependencies.  There are some differences needed because we can
scan dependencies without explicit preprocessing, and can directly
compile the original source afterward.
