refactor(neoverse-rd): define naming convention for CSS macros

As part of the refactoring for the second generation of platforms,
introduce a naming convention for macros within nrd_css_def2.h and
nrd_css_fw_def2.h. All macros, except those related to page table
entries, must adhere to the format NRD_CSS_<name>. Page table entry
macros are handled separately and are not part of this patch.

refactor(sgi): replace references to "SGI"/"sgi" for neoverse_rd

Currently, there are several reference to "SGI" or "sgi" in comments or
as macro prefix within the neoverse_rd directory. As part of the
migration to neoverse_rd, rename all occurences of "SGI/sgi" to
"Neoverse-RD" or the "NRD" prefix accordingly. All references in
comments are rephrased as "Neoverse RD platforms". References in code
are renamed as "NRD"/"nrd" accordingly.

refactor(sgi): move apis and types to "nrd" prefix

Currently, functions and types internal to "neoverse_rd" platforms are
named with "sgi" as the prefix. Since common code and platforms are no
longer under the "sgi" umbrella, move the prefix to "nrd". This change
would amend the prefixes for functions, types and objects.

refactor(sgi): move neoverse_rd out of css

Currently, neoverse_rd is hosted under the "css" directory. However,
"css" directory is more relevant for hosting css definitions and
corresponding sources. Since neoverse_rd hosts source and header for css
and soc, move neoverse_rd from css to board folder. Consolidate common
sources and headers under neoverse_rd/common. Additionally, group RD-V1,
RD-V1-MC, RD-N2, RD-N1-Edgex2 and SGI-575 within neoverse_rd/platform.
