Subject: [meta-mingw][kirkstone][PATCH] toolchain-scripts-mingw32.bbclass: Remove trailing slash in SDKROOT

Modify toolchain-scripts-mingw32.bbclass to add a check in environment-setup script which removes trailing slash in path of SDKROOT.
This is needed to avoid multiple adjacent slashes in paths which are produced by appending to SDKROOT.
In reference to https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file?redirectedfrom=MSDN
naming convention used for paths and disk drives in windows should use a single backslash. Even though in some cases windows ignores double slashes in paths and it might work but it isn't documented as a right naming convention and does fail in some cases eg. dir command cannot interpret double slashes and fails.

For example if my SDK is located in D: drive, the environment setup scripts sets "SDKROOT=D:\" and hence SDKTARGETSYSROOT gets set as "SDKTARGETSYSROOT=D:\\sysroots\armv8a-oe-linux"
The introduced check removes additional slash in SDKROOT to set it as "SDKROOT=D:" so all other variables using SDKROOT get set without additional slash.
