Subject: [PATCH 1/2] tools/perf: Add text_end to "struct dso" to save .text section size

From: Athira Rajeev <[email-masked]>
Date: Fri, 11 Aug 2023 10:51:27 +0530

Update "struct dso" to include new member "text_end".
This new field will represent the offset for end of text
section for a dso. This value is derived as:
sh_size (Size of section in byes) + sh_offset (Section file
offst) of the elf header for text.
