Replace the original diag implementation in idf.py with the new one in a
separate esp-idf-diag python package. The interface is kept the same as
it was. The simple idf.py diag test is also preserved.

At present, the diag tool uses its default purge file. However, users
may find it beneficial to specify and reuse their own purge file. A new
command line option, --purge, has been introduced to allow users to
provide their own purge file to diag. When this option is used, the
default purge file is ignored.

This should enable the collection of more detailed information about the
operating system and basic CPU details.

At present, the steps are executed unconditionally. With this
modification, we can restrict each step individually to determine if it
should run on a particular system. For instance, we can execute
different commands on different systems. This is achieved by adding a
new key, "system," to the step dictionary, with possible values being
Linux, Windows, and Darwin.

Currently, if a command run by the exec command returns an error
code, its stdout and stderr are not saved. It could be beneficial to
store at least the stderr if requested. Additionally, avoid creating
output files when there is no content and also store the stderr
of the failed command to diag.log.

When a symbol needs to be placed to a different target than the one
designated for the object file, the object file is expanded, which
includes the following steps:
1. Creating a new placement for the symbol's input section with the
specified target.
2. Excluding the object placement from the orignal target.
3. Creating a new intermediate placement for the object for the original
target, where its input sections are expanded, excluding the input
section for the symbol.
Let's illustrate the object expansion process with the following example:
[sections:rodata]
entries:
.rodata+
.sdata2+
.srodata+
[scheme:default]
entries:
text -> flash_text
rodata -> flash_rodata
[scheme:noflash]
entries:
text -> iram0_text
rodata -> dram0_data
[mapping:soc_pm]
archive: libsoc.a
entries:
gpio_periph: GPIO_HOLD_MASK (noflash)

1. Creating a new placement
.dram0.data :
{
*libsoc.a:gpio_periph.*(.rodata.GPIO_HOLD_MASK .sdata2.GPIO_HOLD_MASK .srodata.GPIO_HOLD_MASK)
}
2. Excluding the object placement
.flash.rodata :
{
*(EXCLUDE_FILE(*libsoc.a:gpio_periph.*) .rodata.* ...)
}
3. Creating a new intermediate placement
.flash.rodata :
{
*libsoc.a:gpio_periph.*(.rodata.GPIO_PIN_MUX_REG)
}
Now, let's do the same, but also move GPIO_PIN_MUX_REG to noflash with an updated mapping.
[mapping:soc_pm]
archive: libsoc.a
entries:
gpio_periph: GPIO_HOLD_MASK (noflash)
gpio_periph: GPIO_PIN_MUX_REG (noflash)
1. Creating a new placement
.dram0.data :
{
*libsoc.a:gpio_periph.*(.rodata.GPIO_HOLD_MASK .sdata2.GPIO_HOLD_MASK .srodata.GPIO_HOLD_MASK)
*libsoc.a:gpio_periph.*(.rodata.GPIO_PIN_MUX_REG .sdata2.GPIO_PIN_MUX_REG
.srodata.GPIO_PIN_MUX_REG)
}
2. Excluding the object placement
.flash.rodata :
{
*(EXCLUDE_FILE(*libsoc.a:gpio_periph.*) .rodata.* ...)
}
3. Creating a new intermediate placement
.flash.rodata :
{
*libsoc.a:gpio_periph.*
}
The *libsoc.a:gpio_periph.* entity in step 3 no longer has input
sections, as there are no remaining .rodata input sections in the object
file. The linker behavior for this mapping is to include all object
input sections that have not yet been placed as described in
https://sourceware.org/binutils/docs/ld.html#Input-Section-Basics
"If you use a file name without a list of sections, then all sections in
the input file will be included in the output section. This is not
commonly done, but it may by useful on occasion."
The map file for such mapping now contains following input sections
.flash.rodata 0x3c0a0120 0x19b34
*libsoc.a:gpio_periph.*()
.debug_info 0x3c0b95bf 0xd8 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_abbrev 0x3c0b9697 0x70 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_aranges
0x3c0b9707 0x18 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_line 0x3c0b971f 0x1ab esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_str 0x3c0b98ca 0x21a esp-idf/soc/libsoc.a(gpio_periph.c.obj)
0x22d (size before relaxing)
.comment 0x3c0b9ae4 0x30 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.note.GNU-stack
0x3c0b9ae4 0x0 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.riscv.attributes
0x3c0b9ae4 0x44 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
This is incorrect, and such intermediate placement should not be
generated. This type of placement can be recognized because it is not
explicitly defined in the mapping and lacks input sections. We can
identify this in the significant function and prevent issuing commands
for such placement.
