Current include logic goes into generic arm v8/v9 architecture tunes and
adds corresponding -march option after synthesizing it from various tune
fragments, this is fine for a machine which is using armv8/armv9 based
tunes but cortex tunes are intentionally using -mcpu option based on
selected tune value. So when cortex based default tune is selected for a
machine, it will add both -mcpu and -march to the compiler commandline
which can result in invalid combinations for this pair in gcc's own
logic. This can then result in compiler warnings/errors reporting this
e.g.
aarch64-yoe-linux-gcc -mcpu=cortex-a72.cortex-a53 -march=armv8-a+crc+crypto -mbranch-protection=standard
...
cc1: error: switch '-mcpu=cortex-a72.cortex-a53' conflicts with '-march=armv8-a+crc+crypto' switch and resulted in options '+crc+crypto' being added [-Werror]
This is seen in lot of configure test results in glibc 2.39 and the
warning is promoted to errors by gcc in some of these checks especially
with gcc-14, the logs also show it as warning in other places in
configure checks.
mcpu option will compute relevant march implicitly as it specifies a cpu
implementation and this will be the right value to use, therefore do not
specify -march when -mcpu is already describing the cpu.

Move all of the tune files found in conf/machine/include into their
respective architecture directories in that same location. All
references to these will need to be updated. So, change the relevant
ones for this tree in this commit as well.
For the ARM tunes, nest them one further into armv8a, armv8m, etc. and
rename some to make them uniform with the rest of the tunes.

This is the result of automated script conversion:
scripts/contrib/convert-overrides.py <oe-core directory>
converting the metadata to use ":" as the override character instead of "_".

Add tunes for all the ARMv8.2a cores currently supported in GCC. This
is: Cortex-A65, Cortex-A65AE, Cortex-A75, Cortex-A76, Cortex-A76AE,
Cortex-A77, Neoverse-E1, Neoverse-N1, Cortex-A75-Cortex-A55, and
Cortex-A76-Cortex-A55.
