The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also removes deprecated code and makes this bootloader
configuration as default for esp32 targets and removes the need
for running 'make bootloader' command for it.

According to Make documentation:
- "Commas and unmatched parentheses or braces cannot appear in the text
of an argument as written";
- "Leading spaces cannot appear in the text of the first argument as
written".
Although in the current state it was not resulting in parsing issues, it
is better to fix it.

This is only useful when the path to binary files (e.g. bootloader) is
provided via the ESPTOOL_BINDIR variable.

This is just a workaround for adding the MCUboot signed binary image to
the clean step of the build system. Once the NuttX build system becomes
aware of general signed images, a new naming pattern should be defined
for the signed images to be used by every platform.

* it wasn't intended.
* it doesn't always work:
(gdb) source tools/esp32/backtrace.gdbscript
(gdb) esp32_bt 0x40139706 0x80139811 0x3ffafd40
Attempt to assign to an unmodifiable value.

That was only to build the bootloader and partition table. Now we have
a repo with pre-built binaries and with instructions on how to
customize the bootloader.

Use the usual while loop idiom when parsing arguments.
Add more options to the script to be able to specify the name of the
NuttX binary and final image.

1. Don't use the bootloader and partition-table
binaries from a hello-world example. Rather the ESPTOOL_BINDIR variable
can be used to give a user-defined location.
2. The ESPTOOL_BINDIR variable has to be as generic as possible. Don't
assume any board configuration.

NUTTXNAME is used only as an alias for "nuttx", not actually a
configuration property. Its definition might erroneously imply that the
name of binary image may be configurable, which is not the case.
Redirect the first check of esptool to /dev/null as it will be printed
twice when esptool is called to convert the binary.
