Log Message: ----------- remoteproc: add checked arithmetic helpers
Add generic checked addition, subtraction, and multiplication helpers with consistent input validation across builtin and fallback implementations.
Add a generic range-containment helper which reports arithmetic overflow separately from non-containment. This lets the ELF loader distinguish malformed ranges from data absent from the current image chunk.

Log Message: ----------- remoteproc: validate ELF header shape before table loading
Reject malformed ELF headers before using program or section table metadata from the firmware image.
Validate the ELF class, ELF header size, program header entry size, section header entry size, and section string-table index. Release an image-info object allocated by this call if validation fails, while leaving caller-owned objects untouched.

Log Message: ----------- remoteproc: check ELF program and section table sizes
Use checked multiplication when computing ELF program and section header table sizes from e_phnum/e_phentsize and e_shnum/e_shentsize.
Also replace wrapping offset-plus-length range checks with overflow-safe image chunk validation before allocation and memcpy. Malformed firmware images with impossible table sizes now fail with -RPROC_EINVAL.

Log Message: ----------- remoteproc: harden ELF section string-table range checks
Use overflow-safe range validation before copying the ELF section string table from the firmware image.
The section string-table offset and size are read from untrusted section headers. Validate that the full table is present in the current image chunk without relying on wrapping offset arithmetic.

Log Message: ----------- remoteproc: track loaded ELF section string-table size
Store the loaded section string-table size in the ELF image information for both ELF32 and ELF64 images.
Keeping the size alongside the string-table pointer allows later section name lookups to validate sh_name offsets against the actual loaded table bounds.

Log Message: ----------- remoteproc: bound ELF section name lookups
Make ELF section-name lookup validate sh_name before reading from the loaded section string table.
Skip malformed section names whose sh_name offset is outside the table or whose string is not NUL-terminated within the remaining table bytes. Use bounded comparison for valid candidates so .resource_table lookup cannot read past the loaded string table.

Log Message: ----------- remoteproc: avoid wrapping loader offset comparison
Replace the non-seekable loader offset comparison that used offset + len with an overflow-safe equivalent.
This preserves existing behavior for normal ranges while avoiding a wraparound case when deciding whether required image data is contiguous with the current chunk.
