Honor --no-size-check when creating file containers via the CLI

Browse Source 
The text-mode volume creation path clamps the maximum allowed volume
size to the available free disk space and never consults
ArgDisableFileSizeCheck, so the documented --no-size-check switch has no
effect when creating a file-hosted container with `--text --create`.

The flag is honored by the GUI wizard (Forms/VolumeSizeWizardPage.cpp)
but was missing from the text UI, making it impossible to create a
(sparse) container larger than the current free space from the command
line -- even though such a container is perfectly valid on filesystems
with sparse-file support (e.g. APFS, ext4, NTFS) and is exactly what the
flag exists to allow.

Skip the free-space clamp when --no-size-check is set, mirroring the GUI
behavior.
