daf866b606 target/riscv: Consolidate RV32/64 32-bit instructions
This patch removes the insn32-64.decode decode file and consolidates the
instructions into the general RISC-V insn32.decode decode tree.

This means that all of the instructions are avaliable in both the 32-bit
and 64-bit builds. This also means that we run a check to ensure we are
running a 64-bit softmmu before we execute the 64-bit only instructions.
This allows us to include the 32-bit instructions in the 64-bit build,
while also ensuring that 32-bit only software can not execute the
instructions.

7687537ab0 target/riscv: Split the Hypervisor execute load helpers
Split the hypervisor execute load functions into two seperate functions.
This avoids us having to pass the memop to the C helper functions.

743077b35b target/riscv: Remove the hyp load and store functions
Remove the special Virtulisation load and store functions and just use
the standard tcg tcg_gen_qemu_ld_tl() and tcg_gen_qemu_st_tl() functions
instead.

As part of this change we ensure we still run an access check to make
sure we can perform the operations.

139c1837db meson: rename included C source files to .c.inc
With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.

Alternatively you can use a fine-grained dependency, e.g.

        target/arm/translate.o: target/arm/decode-neon-shared.inc.c

With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.

The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.

Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files.  The editorconfig
file is adjusted.
