Added XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE variable which
sets the scheme property value for "GPU Frame Capture" in the Options section by setting the Xcode project variable "enableGPUFrameCaptureMode".
Example values are "Metal" (1) and "Disabled" (3).
XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE is initialized by the property CMAKE_XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE.
Implements: #22700
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
Add `XCODE_SCHEME_*` target properties and associated variables
`CMAKE_XCODE_SCHEME_*` to initialize them on target creation.
Map each target property value to an associated Xcode scheme entry.
