Build settings for Debug F446 Nucleo64 have errors

[fitch22]

The build settings for Debug F446 Nucleo64 are broken. The Build Artifact name should be "grblHAL F446 Nucleo". The linker script called out has a hard coded path to someone's computer and that path does not exist for me. The linker script setting should be "${workspace_loc:/${ProjName}/STM32F446RETX_FLASH.ld}". There could be other things but with these changes I can build with this configuration.
