build: permit multiple linker scripts
This change allows platforms to provide more than one linker script to
any image utilizing the `MAKE_BL` build system macro.
This is already done by some MediaTek platforms via the
`EXTRA_LINKERFILE` build system variable, which has now been removed.
In its place, additional linker scripts may be added to the
`<IMAGE>_LINKER_SCRIPT_SOURCES` variable.
BREAKING-CHANGE: The `EXTRA_LINKERFILE` build system variable has been
replaced with the `<IMAGE>_LINKER_SCRIPT_SOURCES` variable. See the
commit message for more information.
