This commit cleans up the section name definitions in the linker sections header file (`include/linker/sections.h`) to have the uniform format of `_(SECTION)_SECTION_NAME`. In addition, the scope of the short section reference aliases (e.g. `TEXT`, `DATA`, `BSS`) are now limited to the ASM code, as they are currently used (and intended to be used) only by the ASM code to specify the target section for functions and variables, and these short names can cause name conflicts with the symbols used in the C code.
