Replace our hard-coded default for `/RTC1` with a first-class
abstraction to select runtime checks from an enumeration of logical
names. Add a `MSVC_RUNTIME_CHECKS` target property and corresponding
`CMAKE_MSVC_RUNTIME_CHECKS` variable.
Removing the old default flag requires a policy because existing
projects may rely on string processing to edit them and choose
runtime checks under the old behavior. Add policy CMP0184 to
provide compatibility.

The Ninja and Makefile generators honor `target_compile_options`
and friends for MASM `.asm` sources. Teach the VS generator to
honor them too for consistency.
Fixes: #24289
In commit 0e96a20478 (MSVC: Add abstraction for debug information
format, 2022-08-25, v3.25.0-rc1~142^2~1) we overlooked populating the
runtime library selection flags for the Microsoft assembler. Its
compiler id is `MSVC`, so our generators expect the table to be
populated. It only supports `Embedded` debug info. Use empty flags for
the other formats.
Without this fix, enabling the `ASM_MASM` language with policy `CMP0141`
set to `NEW` causes an error due to the missing table entries.
Fixes: #24249
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.
