Subject: capture/replay: interface implementation 1 (#4122)

* capture/replay: interface implementation 1

- Add global session, filesystem, and session capture interface classes:
    GlobalSessionCapture for IGlobalSession
    FileSystemCapture for ISlangFileSystemExt
    SessionCapture for ISession

- Add environment variables to enable it
    The 2 variables are SLANG_CAPTURE_LAYER and SLANG_CAPTURE_LOG_LEVEL

    SLANG_CAPTURE_LAYER:

    In slang_createGlobalSession(), after the compiling/loading stdlib,
    we will check the capture environment variable, if it's set to 1,
    we will create a GlobalSessionCapture object and return to user
    code.

    SLANG_CAPTURE_LOG_LEVEL: This is to set the log level, user can
    choose the loglevel to debug. (We can remove this when the feature
    is fully implemented).

- Update premake file and cmake file to add the capture/replay source folder

* Fix Windows build error

Fix windows build error by adding the "SLANG_MCALL" keyword.
Change to use Slang::ComPtr for those captured object pointers
to simplify the resource management.

Use __func__ macro to print the function name in the log.
