[Feature] Add GDAL backend and Support LEVIR-CD Dataset (#2903)
## Motivation

For support with reading multiple remote sensing image formats, please
refer to https://gdal.org/drivers/raster/index.html.

Byte, UInt16, Int16, UInt32, Int32, Float32, Float64, CInt16, CInt32,
CFloat32 and CFloat64 are supported for reading and writing.

Support input of two images for change detection tasks, and support the
LEVIR-CD dataset.

## Modification

Add LoadSingleRSImageFromFile in 'mmseg/datasets/transforms/loading.py'.
Load a single remote sensing image for object segmentation tasks.

Add LoadMultipleRSImageFromFile in
'mmseg/datasets/transforms/loading.py'.
Load two remote sensing images for change detection tasks.

Add ConcatCDInput  in 'mmseg/datasets/transforms/transforms.py'.
Combine images that have been separately augmented for data enhancement.

Add BaseCDDataset in 'mmseg/datasets/basesegdataset.py'
Base class for datasets used in change detection tasks.
