Style: Make Renesas RXv3 DPFPU port layer consistent with uncrustify.

[NoMaY-jp]

Description

The following changes are made.

Add '/* *INDENT-OFF* */' and '/* *INDENT-ON* */' around inline assembly code in C source files.
Add above comments around '#ifdef __cplusplus extern "C" #endif' in portmacro.h.
Add above comments around '#ifdef __cplusplus } #endif' in portmacro.h.
Add '; /* *INDENT-OFF* */' at the top of assembly source file.
Remove '1 tab == 4 spaces!'.
Change tab to spaces.
Beautification by uncrustify.
Beautification by hand (no conflict with uncrustify).
Fix inconsistency which I didn't notice at the commit 386d854: DFPU --> DPFPU.

The following uncrustify and config file are used.

uncrustify: uncrustify-0.71.0_f-win32
config: FreeRTOS/tools/uncrustify.cfg

Test Steps

There are no changes in the MOT and SREC files (the following total 2 * 3 * 3 = 18 cases) which are built for Renesas RX72N Envision Kit RTOS Demo between before and after.

Total 2 * 3 * 3 = 18 cases:

(1) Define/not define USE_FULL_REGISTER_INITIALISATION in FreeRTOSConfig.h
(2) Define configUSE_TASK_DPFPU_SUPPORT = 1, 2, 0 in FreeRTOSConfig.h
(3) GNURX, CC-RX, ICCRX

Style: Revert uncrustify for portable directories #115
#115 (comment)

In addition to a small tip in the above conversation for embedding /* *INDENT-OFF* */ into Renesas CC-RX's assembly source file (*.src), I notice that there is another tip to do it. The following source file is fortunately consistent with uncrustify. But I'm not sure whether it may cause some other problems or not.

Especially there are two spaces between ';' and '*', for example:

;  * FreeRTOS Kernel V10.3.1

instead of one space between ';' and '*', for example:

; * FreeRTOS Kernel V10.3.1

It may happen that two spaces will be re-formatted to one space by other tool or script.

Hello,

I close this PR because of new conversations between I and Renesas Electronics Corporation about new another port and it will make this PR unused.

Best regards,
