Add support for building rocgdb from external source directory

[lumachad]

This enables developers to build rocgdb from a custom source location while preserving the TheRock wrapper infrastructure, supporting local development and testing of rocgdb modifications.

This could use the therock_enable_external_source functions or follow how we handle it for rocm-systems as well as rocm-libraries:

TheRock/CMakeLists.txt

Lines 139 to 151 in fc07dec

	# Use the rocm-libraries superrepo tracked in TheRock's `.gitmodules` or
	# allow to specify an alternative source location.
	set(THEROCK_ROCM_LIBRARIES_SOURCE_DIR_DEFAULT "${THEROCK_SOURCE_DIR}/rocm-libraries")
	set(THEROCK_ROCM_LIBRARIES_SOURCE_DIR "${THEROCK_ROCM_LIBRARIES_SOURCE_DIR_DEFAULT}" CACHE STRING "Path to rocm-libraries superrepo")
	cmake_path(ABSOLUTE_PATH THEROCK_ROCM_LIBRARIES_SOURCE_DIR NORMALIZE)
	set(THEROCM_ROCM_SYSTEMS_SOURCE_DIR_DEFAULT "${THEROCK_SOURCE_DIR}/rocm-systems")
	set(THEROCK_ROCM_SYSTEMS_SOURCE_DIR "${THEROCM_ROCM_SYSTEMS_SOURCE_DIR_DEFAULT}" CACHE STRING "Path to rocm-systems superrepo")
	cmake_path(ABSOLUTE_PATH THEROCK_ROCM_SYSTEMS_SOURCE_DIR NORMALIZE)
	# Allow to specify alternative source locations instead of using
	# repositories tracked in TheRock's `.gitmodules`.
	therock_enable_external_source("composable-kernel" "${THEROCK_SOURCE_DIR}/ml-libs/composable_kernel" OFF)

Commit 5523139 removes the function use for rccl (which was moved into rocm-systems) but that might give you an idea how this works. Happy to jump on a call if needed.

Let me adjust this then.

Updated to use a similar scheme to rocm-systems.
