build: clarify linker script generation
The following build system variables have been renamed:
- `LINKERFILE` -> `DEFAULT_LINKER_SCRIPT`
- `BL_LINKERFILE` -> `DEFAULT_LINKER_SCRIPT_SOURCE`
- `<IMAGE>_LINKERFILE` -> `<IMAGE>_DEFAULT_LINKER_SCRIPT_SOURCE`
These new names better reflect how each variable is used:
1. the default linker script is passed via `-dT` instead of `-T`
2. linker script source files are first preprocessed
Additionally, linker scripts are now placed in the build directory
relative to where they exist in the source directory. For example,
the `bl32/sp_min/sp_min.ld.S` would now preprocess to
`sp_min/sp_min.ld` instead of just `bl32.ld`
BREAKING-CHANGE: The `LINKERFILE`, `BL_LINKERFILE` and
`<IMAGE_LINKERFILE>` build system variables have been renamed. See the
commit message for more information.
