legal: Replace and relocate Apache-2.0 LICENSE to comply reuse

[rzr]

Note content of file has been changed, It is a good practice to align to Original files they are validated and trusted by SBOM tools that verify checksums (bitbake for instance),

For the record:

Checksums-Sha256: eb0aad9b316fb87f01ec635a13ad59d63bf5cdbb90419ea4e62c11c19c5edeea LICENSE-Apache-2.0 Checksums-Sha256: 074e6e32c86a4c0ef8b3ed25b721ca23aca83df277cd88106ef7177c354615ff LICENSES/Apache-2.0.txt

Note file has been downloaded using:

Note that Pelion copyright can not apply to the context of text of Apache work, (i believe it is a mistake) the copyright is tracked on sources codes.

Current Reuse status is:

• Missing licenses: GPL-2.0
• Used licenses: Apache-2.0, GPL-2.0, LicenseRef-MSLA
• Files with copyright information: 272 / 309
• Files with license information: 272 / 309

This version is not formatted in 80 columns. Could we use this one: https://www.apache.org/licenses/LICENSE-2.0.txt

I used the one provided by reuse , I believe this checksum is known as reference for related sdpx tools so I aligned to it:

$ curl https://raw.githubusercontent.com/spdx/license-list-data/main/text/Apache-2.0.txt | sha256sum | grep 074e6e32c86a4c0ef8b3ed25b721ca23aca83df277cd88106ef7177c354615ff

It looks like spdx uniformized style of licences to make it more consistent (and more semantic?).

Style is very subjective, is it blocker for this PR ?
