Added various features

[PQCraft]

tools/cxbe:

• Added the ability to handle long section names (moved the limit from 8 chars to 255)
• Added an option to set the XBE's title ID to either a hex code (like FFFF0002) or a human-readable code (like CX-9999)
• Added an option to set the XBE's region flags
• Added an option to set the XBE's version (can be dec, hex, or oct)

Makefile:

• Added XBE_TITLEID to define a title ID (goes to cxbe as -TITLEID:$(XBE_TITLEID))
• Added XBE_REGION to define a title ID (goes to cxbe as -REGION:$(XBE_REGION))
• Added XBE_VERSION to define a title ID (goes to cxbe as -VERSION:$(XBE_VERSION))

I haven't given this an in-depth review yet, but here's some preliminary feedback:

tools/cxbe:

This commit contains multiple separate changes and should be split up, with each commit introducing one feature and a short but descriptive commit title following the style of previous commits.

lib/pbkit:

The printing functionality in pbkit is a bit of a legacy feature - pbkit is currently a wild mix of high- and low-level code, and the printing code is most likely going to be removed soon-ish, so imho it doesn't make much sense to add features to it. It's only still here because it can help with debugging.
If you need a way to print text, I'd suggest having your own printing code in your app (potentially using the current pbkit code as a starting point).

Makefile:

The makefile is a remnant from the early days of nxdk, I'd actually recommend against using it for anything other than building nxdk itself. We've been working on removing the need for it by adding wrapper scripts for the compiler and CMake support, and we'll eventually remove it.
For the moment, if you rely on the features you added, I'd recommend adding them as overrides to your own makefile and including the nxdk makefile like the samples do, but the most future proof solution is supplying your own independent makefile.

* Added an `objcopy` line after the linking stage to redirect `XTIMAGE` to `$$XTIMAGE` and `XSIMAGE` to `$$XSIMAGE` (it is impossible to define these sections otherwise)

Hmmm, interesting. I'll try to find some time to experiment with this, but if there really is no other way we should probably put that info into the nxdk wiki.

This review might sound a bit negative, but be assured that I really do appreciate people upstreaming fixes and features 👍

Splitting up the commits for cxbe might take a bit since I will need to go into the code and manually undo the changes in reverse order then redo them

For pbkit, I'll probably steal pbkit's text functions directly and paste them into my rendering code lol

For the Makefile, I am relying on calling it from my actual Makefile using this little snippet:

    ...
    else ifeq ($(CROSS),xbox)
        ifndef NXDK_DIR
            .PHONY: error
            error:
	            @echo Please define the NXDK_DIR environment variable
	            @exit 1
        endif
        ifneq ($(MODULE),engine)
            .PHONY: error
            error:
	            @echo Invalid module: $(MODULE)
	            @exit 1
        endif

        PLATFORM := Xbox

        export XBE_TITLEID := PQ-001
        export XBE_VERSION := $(shell grep '#define PSRC_BUILD ' src/version.h | sed 's/#define .* //')
        export GEN_XISO := $(XBE_TITLE).xiso.iso

        SRCS := $(SRCS) $(wildcard $(SRCDIR)/psrc_server/*.c)
        SRCS := $(SRCS) $(wildcard $(SRCDIR)/stb/*.c)
        export SRCS
        export NXDK_SDL = y

        MKENV := ${MKENV} OUTPUT_DIR=xbox
        CPPFLAGS := $(CPPFLAGS) -DSTBI_NO_SIMD -DPB_HAL_FONT
        ifdef DEBUG
            CFLAGS := $(CFLAGS) -Og -g
            CPPFLAGS := $(CPPFLAGS) -DDBGLVL=$(DEBUG)
            MKENV := ${MKENV} DEBUG=y
        else
            ifndef O
                O = 2
            endif

            ifndef NOLTO

            endif
        endif

        export CFLAGS := $(CFLAGS) $(CPPFLAGS)
        export LDFLAGS

        xbox-build:
	        @$(MAKE) --no-print-directory -f $(NXDK_DIR)/Makefile ${MKENV}

        xbox-clean:
	        @$(MAKE) --no-print-directory -f $(NXDK_DIR)/Makefile ${MKENV} clean

        xbox-distclean:
	        @$(MAKE) --no-print-directory -f $(NXDK_DIR)/Makefile ${MKENV} distclean

        .PHONY: xbox-build xbox-clean xbox-distclean
    else
    ...

For the $$XTIMAGE and $$XSIMAGE sections, putting a $ in the section name causes the linker to remove everything after the $ and the $ itself (my$sect -> my). I think it's for some special Windows stuff with shared libraries but the linker does it regardless of the output. Also the linker will truncate any section longer than 8 chars and these sections are both 9 chars. It isn't possible to tell the linker to stop modifying section names or to allow long section names so you have to edit the binary after linking using an external tool (like objcopy).

Ok @thrimbor I split up the cxbe commits and also removed the changes to pbkit 👍

[PQCraft]

@JayFoxRox I fixed all of the issues I think

[PQCraft]

IDK how to make the "This branch cannot be rebased due to conflicts" message go away so I'm going to open a new PR and see if that works.
