refactor: redefine bundle.total_space (#19221)

Use a custom structure for bundle.total_space.
- Use bundle.total_space.mk instead of bundle.total_space_mk.
- Use bundle.total_space.to_prod instead of equiv.sigma_equiv_prod.
- Use bundle.total_space.mk' (scoped notation) to specify F.
- Rename bundle.trivial.proj_snd to bundle.total_space.trivial_snd to allow dot notation. Should we just use bundle.total_space.snd since bundle.trivial is now reducible?
Add an unused argument to bundle.total_space.
Make bundle.trivial and bundle.continuous_linear_map reducible.
Drop instances that are no longer needed.

chore(*): remove empty lines between variable statements (#11418)

Empty lines were removed by executing the following Python script twice

import os
import re


# Loop through each file in the repository
for dir_path, dirs, files in os.walk('.'):
  for filename in files:
    if filename.endswith('.lean'):
      file_path = os.path.join(dir_path, filename)

      # Open the file and read its contents
      with open(file_path, 'r') as file:
        content = file.read()

      # Use a regular expression to replace sequences of "variable" lines separated by empty lines
      # with sequences without empty lines
      modified_content = re.sub(r'(variable.*\n)\n(variable(?! .* in))', r'\1\2', content)

      # Write the modified content back to the file
      with open(file_path, 'w') as file:
        file.write(modified_content)

chore: remove tactics (#11365)

More tactics that are not used, found using the linter at #11308.

The PR consists of tactic removals, whitespace changes and replacing a porting note by an explanation.
