fix(mediatek): covert MTK_BL to uppercase for the build

The build macro no longer coverts variable names to uppercase.
We need to convert it to uppercase to pass it on.

build: consolidate directory creation rules

This commit streamlines directory creation by introducing a single
pattern rule to automatically make directories for which there is a
dependency.

We currently use several macros to generate rules to create directories
upon dependence, which is a significant amount of code and a lot of
redundancy. The rule introduced by this change represents a catch-all:
any rule dependency on a path ending in a forward slash is automatically
created.

Now, rules can rely on an unordered dependency (`|`) on `$$(@D)/` which,
when secondary expansion is enabled, expands to the directory of the
target being built, e.g.:

build/main.o: main.c | $$(@D)/ # automatically creates `build/`

build: add string casing facilities to utilities

This is a small modification to two existing functions in the build
system: `uppercase` and `lowercase`.

These functions have been moved to the common utilities makefile, and
use the `tr` tool to simplify their implementation. Behaviour is, for
virtually all use-cases, identical.

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.

Provide six initcall levels for drivers/modules initialize HW
controllers or runtime arguments during cold boot.

The initcall level cold boot execution order:

-MTK_EARLY_PLAT_INIT
Call before MMU enabled.

-MTK_ARCH_INIT
MMU Enabled, arch related init(GiC init, interrupt type registration).

-MTK_PLAT_SETUP_0_INIT
MTK driver init level 0.

-MTK_PLAT_SETUP_1_INIT
MTK driver init level 1.

-MTK_PLAT_RUNTIME_INIT
MTK driver init. After this initcall, TF-A handovers to MTK 2nd
bootloader.

-MTK_PLAT_BL33_DEFER_INIT
MTK 2nd bootloader traps to TF-A before handover to rich OS.
This initcall executed in the trap handler(boot_to_kernel).
