twister: check if qemu binary file exists and if it is executable, and throws an error message if it is not

[wangnuannuan]

When the qemu binary file doesn't exist or it is unexecutable, the cmake will not throw error message when build, it will throw error when run command west build -t run.

$ west build -t run
-- west build: running target run

Also the twister can't detect this error, then the twister will hang forever.
