cmake: drop OE specific environment variable support

CMAKE_TOOLCHAIN_FILE is now also a supported environment
variable, we can export it directly. There's no need to
use a OE specific patch to add OE_CMAKE_TOOLCHAIN_FILE
support.

-Subject: [PATCH] CMakeDetermineSystem: use oe environment vars to load default
- toolchain file in sdk
-
-Passing the toolchain by:
-
- - shell aliases does not work if cmake is called by a script
- - unconditionally by a wrapper script causes cmake to believe it is
-   configuring things when it is not (for example, `cmake --build` breaks).
-
-The OE_CMAKE_TOOLCHAIN_FILE variable is only used as a default if no
-toolchain is explicitly specified.
-
-Setting the CMAKE_TOOLCHAIN_FILE cmake variable is marked as cached
-because '-D' options are cache entries themselves.
-
-Upstream-Status: Inappropriate [oe-core specific]
